The Polaris is a low to medium gain overdrive with a unique set of features. Building on top of an impressive overdrive, the Polaris features a unique filter feature accessible via the Filter control or expression pedal connection. Three filter options allows you to dive in and interact with the Polaris directly and sweep through different filtered voices. The Polaris introduces a distinct layering effect with the Initial control that can be used to mix in your pre-filtered overdrive tone for some fuzzy undertones as you play along. With unique tonal settings and plenty of experimentation to be had, the Polaris invites you to get in on the spacious, overdriven action.

Spaceman Titan II Fuzz Effects Pedal The Titan II Fuzz Machine is a unique discrete circuit using silicon transistors.  Despite only having three control parameters, the Titan II packs a wide array of distinct tones within its cast aluminum shell. Named after the NASA rocket that launched the Gemini manned space missions, the Titan II has arrived to blast your tone into the stratosphere! FUZZ, DISTORTION, OVERDRIVE… The Titan II is a unique discrete circuit using silicon transistors. Despite only having three control parameters, the Titan II packs a wide array of distinct tones within its aluminum shell. At full bore, you will get splatty, nasty fuzz tones; but the wide-range Gain control also delivers great low gain tones that start to crossover into overdrive territory. Furthermore, in-between these extremes exist fuzz-tinged distortion tones as well. SIMPLE CONTROLS, COMPLEX RESULTS For even more tonal variety, the Titan II cleans up nicely with the volume on your instrument, adding additional levels of fuzz textures and expression. The Tone control offers a complex tonal shift, allowing the Titan II to cover an incredible range of tone and texture. The Titan II sounds awesome with standard, bass and baritone guitars, as well as most things you plug into it.  

An overdrive for guitarists needing their amp to sound great at any volume. The all jFet design stacks well with other overdrives, pushes your tube amp for more sustain, and  most importantly sounds great on its own through a clean amp at any volume.

World’s first octave modulator / octave shift pedal. World’s first shepard tone guitar synthesizer. LFO and envelope octave shifting. All analog filter design. Inspired by old school synthesizers and the 8 bit computing era. The first ever guitar synth with octave modulation So what the heck is octave modulation? The octave theory seamlessly crossfades between octaves. Paired with an awesome filter this creates a multitude of possibilities. like 8 bit chiptune sounds, classic guitar synth, super sub bass tones and the world’s first ever shepard tone guitar synthesizer. With great power… An array of knobs covered many early 1980s synthesizers. This gave you the power to create a wide range of sounds. Of course, on some settings the synthesizer wouldn’t make a sound, would go into uncontrollable oscillation, or make weird noises. Sometimes the weird noises weren’t the weird noises you expected. While many guitarists enjoy tweaking and honing their tone most of us don’t have that level of patience for fiddling with a matrix of interactive settings. The Octave Theory strikes the perfect balance giving you the power to create your own sound without endless knob tweaking or (gasp!) a tedious menu driven interface. The Filter: Resonant filter inspired by the Korg MS20. Like the MS20 the resonance knob can push the Octave Theory into oscillation. Most guitar synth pedals won’t let you go there. They think you can’t handle so much raw power. To be fair many of those filter oscillation sounds can get shrill or overbearing. If you keep the filter frequency low you can give your synth tones some growl. Use this power responsibly.  AMP vs. Filter priority and envelopes. ADSR envelopes are a mainstay of synthesizers. While lacking full external ADSR control an internal ADR (Attack/Decay/Release) envelope is generated to control the oscillator output level. (AMP – synthspeak for modulating the oscillator output level.) AMP Priority (white marker): In modes with the white marker the decay knob gives you full control of the AMP decay. In these modes the filter also follows the ADR envelope at a fixed depth. This allows you to make notes decay quickly and gracefully. Turning the knob up allows for longer decay times. Filter Priority (green marker): In green marker modes the filter follows an envelope generated by the strength of the input. (The same way envelope filters work) The depth knob controls how much influence the the input envelope has over the filter. When in filter priority the internal ADR envelope is fixed with infinite decay time. Octave Modulation: Modulate your octaves in four ways. LFO modulation, envelope modulation, shepard tone, or manual mode. LFO: This is where you’ll find the chiptune sounds, especially with the square and double square wave modes.In the triangle, square and double square modes the filter follows the internal ADR and the freq knob. In random Mode the filter follows the LFO. The octave mod knob controls the LFO speed. Envelope: Playing dynamics modulate the octave cross fade.  The octave mod knob controls the envelope’s overall influence.  Shepard Tone:  As you work your way up the guitar neck playing higher notes, the octave cross fade descends. When set = modes playing one octave higher will produce the same note. You can play up the neck forever and arrive at the same pitch whether you are playing an open low E or the high E string on the twelfth fret. In ↓ modes the output pitch will get lower and lower as you play higher up the neck. In all shepard tone modes the oct. mod knob manually controls the octaves from several octaves down to several octaves up. Manual mode: This is most similar to our original guitar synth pedal, the Octasynth, but with the most requested feature added. Instead of the Octasynth’s blend control which only allowed for one or two octaves down, the oct. mod knob takes you from three octaves down to two octaves up.

Once again we’ve knocked the world of filter pedals off its axis. Autowah, envelope filter, step filter, random sample/hold filter, even a pixelated envelope filter. This one does it all. After a year in development we present The Prometheus DLX. An analog filter with digital control. We made sure to not build in any artificial limitations. The filter sweep goes above and below normal guitar frequencies, and works well with other instruments such as bass and synthesizers. Select between lowpass, bandpass and highpass filters, and virtually unlimited ways to manipulate them. We took the mad science of the original Prometheus and multiplied it, adding features that not only increase the sonic possibilities, but also make it easier to use. The DLX is a re-imagined Prometheus that uses all the knowledge we gained from The Quasar DLX, and our experience making the most exciting filter pedals in the world. We also added some improvements. More resonance? Yep! Tap tempo? You got it! For even more headroom the DLX will operate at 18 volts. There’s even an internal switch to add a dry signal blend to the bandpass filter. (See, we love you bass players too!) While the options are nearly infinite, we made sure to keep things simple enough so that the average guitar player could figure them out in a few minutes. The Prometheus DLX has nine basic functions: Analog envelope – forward and reverse. Step – tap tempo step filter based on 7 LFO shapes. Trigger LFO – tap to trigger one LFO cycle. Manual LFO – Manually control LFO speed. Warp LFO – tap tempo LFO speed with wave shape warp. Pixilated Envelope – sample/hold envelope control. Envelope Trigger – Envelope triggers LFO. Envelope->LFO manual – Envelope drives LFO speed. Fixed sensitivity. Envelope->LFO – Envelope drives LFO speed. Variable sensitivity. In each of these settings, the WARP control and TAP/HOLD serve different purposes to get the most out of each effect. The expression pedal input can be used with any non-envelope functions. Depending on the shape & mode settings the expression pedal has a different effect. For example, in trigger LFO mode the LFO shape is mapped to the expression pedal. Select the ramp wave for a “standard wah” effect. Choose the saw wave for a reverse wah. The triangle/square wave is especially strange. We also made major improvements to the step filter in the DLX. We not only added tap tempo, but the underlying LFO rate is locked to the step rate. If the step rate changes, there is no need to readjust anything to keep the same arpeggiated pattern. The warp knob is used to adjust the ratio of the step rate and the underlying LFO between 1:1 and 1:1.5. This ensures that there are no redundant settings. Notes about The Prometheus DLX: Powered by an external regulated 9VDC to 18VDC adapter with a negative center 2.1mm barrel style plug. Power supply is not included. If using a “daisy chain” power supply all other pedals MUST be negative ground. Current draw is less than 100mA. Length 4.7″ x Width 3.7″ x Height 1.2″ Input impedance- 1M Output impedance- Less than 1K. The Prometheus DLX is hand made in Oregon. Die cast metal enclosures for durability. 3PDT switches for true bypass switching. Red/Green LED indicator. Three-year limited warranty July 2015- Version 1.5 update: The most versatile filter pedal on earth just got better.The improvements include: More consistent settings between 9 and 18 volt operation. Minor changes and smoothing of the analog envelope follower Improved power filtering

The Quasar v4 offers eleven modes paired with a simple control surface. An abundance of non-traditional options are on tap. Rhythmic modulation patterns. Sci-fi discombobulation. Envelope speed control. Traditional phaser and rotary tones are in the box too, but you want more, right? Something different? Something that stands out? All analog phaser. Synchronized tremolo and chopper effects. Active volume regulation. This eliminates the drastic volume disparities typical of many phasers. Wide range of traditional and experimental sounds. Subdecay has been designing and building Quasar phasers since 2005. For the new Quasar we explored new territory. We love defying effects conventions and breaking the rules. The Quasar’s next evolution is here and we’ve built in so much more than before. Many of the new features are normally only found in fully digital effects. A wide variety of options are under your control. Pairing the analog and digital world together means there’s no compromise of analog headroom or that organic swirl that digital units just can’t match. Modes & Controls: In most modes the controls do what you’d expect. The offset knob is the exception. The offset knob is mode dependent. It sets anything from the phaser sweep center point to synchronized modulation ratios. Rate: Always controls modulation speed.Depth: Controls modulation depth.Color: Usually controls phaser resonance. In mode 5 it controls a portamento function.Mode: Set to any of the eleven modes. Modes are broken down into four categories: 1-4 Cross modulation (X-MOD)5-6 Step Sequencing (STEP)7-8 Envelope (ENV)9-11 Traditional X-MOD: Cross modulation is our fancy way of saying the effect is modulated two different ways at the same time. 1 & 2 -Triangle + Sine & Triangle + Square:The phaser is modulated by a slow triangle LFO and a faster Sine or Square wave LFO.Offset: Sets LFO ratio to 2, 4, 8, 16 or 32. 3 – X-Fade:A cross fade effect. This is kind of like when the radio DJ fades out from one song and into the next one, but instead this crossfades the phaser effect and the clean signal.Offset: Controls how often the effect crossfades over each cycle of the phases. Set to a ratio of 2, 4, 8, 16 or 32.Depth: Controls the cross fade depth. 4 – Tremolo:Synchronized phaser and tremolo.Offset: Sets tremolo ratio to 2, 4, 8, 16 or 32.Depth: Controls tremolo depth. Step Sequencer: Rather than traditional smooth phasing these modes create rhythmic phaser/filter patterns. 5 – Step Pattern:A stepping pattern based on a triangle waveform.Offset: Sets how far steps skip ahead on the triangle waveform creating repeating patterns.Color: Portamento control. Turn to the left to soften step patterns. Turn all the way to the left and modulation will smoothly glide from each step to the next step creating a myriad of unique wave forms. 6 – RND:Random Phaser sequencer with volume chopper (square wave tremolo)Offset: controls how long the volume is chopped per step. (0 – 50%) Envelope modes: Modulation is manipulated by touch dynamics. 7 – Envelope speed control:A phaser effect where the modulation speed is altered by playing dynamics. (Similar functionality to our Vagabond Tremolo, and (discontinued) Siren Vibrato.)Offset: slows down or speeds up modulation when you hit the guitar strings. 8 – Envelope Phaser:Similar to an envelope filter… but with a phaser.Offset: Controls phaser resting point.Depth: Controls how much playing dynamics modulate the phaser (just like an envelope filter.)Rate: Controls envelope attack and decay speed. Traditional: 9 – Rotary / Vibrato:Inspired by the long discontinued DOD FX22 with a deceptively huge range going from straight tremolo or vibrato, to very present filter/phaser tones.Offset: Controls tremolo depth.Color: Turn to the right for resonance. Turn to the left for a pitch vibrato effect. 10 – Slow Triangle LFO:Long linear phaser sweep perfect for slow speeds.Offset: controls center point of modulation. 11 – Fast Sine LFO:A faster phaser using a sine wave LFO.Offset: controls center point of modulation.

Spring reverb and bonus “room” reverb mode. Decay control to dampen or expand reverb. Retain your tone with all analog clean signal path. Trails option when bypassed Separate controls for the reverb and dry signal levels. Redesigned preamp for tube like dynamics and feel. Tone control for subtlety or in your face splash. By analyzing the design, sound and physics of real spring tanks we captured the nuances of tube driven spring reverb. Even something as innocuous as unplugging your guitar cable (kerplangagnangang)  sounds like real deal. A tone control allows you to dial in the perfect timbre. There is also an internal reverb send trimmer serving two purposes- 1. It allows you to turn down for hotter input signals. 2. It does essentially what the dwell control does on an outboard reverb tank. You can turn it up for a more dramatic effect or back it off for subtlety. Unlike a real spring tank the the decay knob allows you to dampen the springs for shorter reverb or bend the laws of physics resulting in long psychedelic resonating trails. The clean signal path is all analog. JFET amplifiers carryout the send and recovery of the reverb signal for even more tube like dynamics. The Super Spring Theory is equally at home in front of a clean or dirty amp. …But wait, There’s more! – Room Reverb There’s also that other reverb setting. ROOM. Don’t think of this as your typical subtle ambiance room reverb. That is certainly possible with the decay knob rolled back. The decay knob alters the dimensions from a broom closet to a cavern covered in ceramic tile with reverb trails over three minutes long. Like no other reverb pedal on earth. Every aspect of the Super Spring Theory was designed from the ground up. You won’t find a “reverb brick” inside. It’s not a datasheet design from someone else.  The Super Spring Theory uses our own DSP reverb algorithms that you can’t get anywhere else. More options In 2011 we set out to create the most realistic spring reverb simulation ever. The Spring Theory was born with authentic sound, feel and dynamics. Since then we’ve been taking notes for the next evolution. We listened and we know what you want. New features are packed in the same pint sized pedal. Now you can hear reverb tails when bypassed. Separate level controls for the dry and reverb sounds along with the new wide range tone control allow for subtle reverb to in your face salt water splash.

PARAGRAPHS is an analog four-pole resonant low pass filter with an attack, decay (AD) envelope generator designed with focus on simplicity and flexibility The heart of the LOW PASS FILTER circuit is the AS3320 analog chip — a modern replica of the same component used in analog classics like the Sequential Prophet 5, Pro-One mono-synth, Elka Synthex, and the LinnDrum. Cutoff spans the full audio spectrum and resonance starts to self-oscillate at about seventy percent.The ENVELOPE GENERATOR offers modulations in an uncommonly wide range of frequencies — starting as low as 0.05 hz for slowly evolving 20 second long cycles, and reaching up to (and past) the audio threshold at 300 hz for a wave shaping effect similar to sounds found on west coast style synthesizers (“think Buchla”).Paragraphs accepts instrument and line level signals. Dedicated controls for input (drive) and output level make it easy to move between a crystal clear clean tone and and a clipping fuzz. A multi-color LED provides a visual representation of the signal level. Red indicates clipping. Orange flashes indicate the start of overload. Green indicates the presence of signal at or below the nominal level.Inputs for CONTROL VOLTAGE and MIDI are available to remotely trigger the envelope generator. This enables your Paragraphs to stay in rhythmic synchronization with external systems like midi sequencers, euroracks, and digital audio workstations -1/4” mono input/output jacks-2.1mm DC Connector-5.7” x 4.7” x 1.5” enclosure dimensions-true bypass-input impedance: 1MΩ-output impedance: <1kΩ-power supply: 9 to 9.6 VDC center negative-current draw: 100mA max

POLYPHRASE is a stereo echo and looping device inspired by early proto-digital delays of the 1970’s like the Lexicon Prime Time. As sophisticated as it is easy-to-use, Polyphrase is capable of everything from rich, dubby rhythmic repeats, to metallic resonant flanges. It is unique in being able to generate loops as long as 22 seconds, opening up a new palette of sonic possibilities for the avant-garde, ambient, or adventurous musician.Polyphrase features two independent SLIDERSfor left and right delay times that can be locked into an infinite feedback loop which will produce an ever-changing sample of audio as each channel overlaps with another. This makes Polyphrase a tool for exploration capable of achieving the same kind of harmonic oscillation found on Steve Reich’s seminal tape piece “Piano Phase”.The TIME knob interacts with the left and right faders by providing nine different maximum delay times starting at 85 milliseconds, and doubling in value as the parameter is increased up to 22 seconds. Each new delay section is cross faded into the signal path, an important design consideration that avoids any pitch shifting artifacts and is useful for creating new and often unexpected musical phrases when used with high repeat settings.Three ECHO STYLES are available, and each style configures its own dedicated routing for the delay feedback path. “Dual stereo” provides two independent echos, and they can either be stacked in mono, or routed out of each stereo channel. In “ping pong” mode, each delay feeds back into the other, creating either a classic stereo ping pong sound (with each repeat bouncing between the left and right channel), or a multi-tap delay effect (when used in mono). The last mode is a mono delay - it routes the feedback path to the IN R, OUT R jacks so that you can use external effects in the echo’s feedback path.The TONE control is a bipolar equalizer (EQ) situated in the feedback path of the echo. At 12 o’clock, the EQ has no effect on the audio. Turning the knob clockwise cuts low end - making each repeat brighter than the previous. Turning the tone knob in the counter-clockwise direction cuts high frequencies - it creates darker repeats, which- makes Polyphrase capable of achieving similar timbre to the storied analog, bucket-brigade delays.The echo signal can be pitch modulated with the RATE and DEPTH controls for a sine wave style chorus / vibrato, or with a random wave for detuning effects similar to aging tape echos.Finally, Polyphrase has a fully featured MIDI INPUT that provides tempo sync, full remote control of all parameters on the faceplate, and access to 9 onboard user preset slots. FEATURES- Delay times from 5 milliseconds to 22 seconds- Two delay lines that can be used in stereo or stacked in mono- Infinite feedback- External feedback path- Tone control in the feedback path- Echo pitch modulation with sine or random style waveform- Tap tempo- Midi tempo sync- 9 onboard user presets accessible via midi program change (PC) messages- Remote control of all parameters on the faceplate via midi continuous controller (CC) messages- 3 gain configurations for line level, instrument level, or low instrument level- Housed in a single block of walnut, CNC routed, hand sanded & polished SPECIFICATIONS- 165mm x 140mm x 45mm- 1/4” mono jacks- Input impedance: 1MΩ- Output impedance: <1kΩ- Current draw: 200mA- Soft-touch foot switches- Buffered bypass    

Dynamic, responsive, tube-like, and amp-like. Walrus Audio is extremely excited to announce the new 385 Overdrive that is boastfully responsible for all those adjectives. For decades now, guitarists in search of pure tone have been taking the tube-powered audio sections of vintage film projectors and using it as a guitar amp. Heads up – it sounds amazing. After endless hours of research on vintage Bell and Howell 385 Filmosound projector, Walrus has created a fantastic new overdrive modeled after the projector’s tone. The Bell and Howell 385 gracefully lends itself to create an amazing guitar amp. Its simple, but effective controls, plus dual 6V6 output section make for a simple and extremely responsive amp that has an amazing compressed overdrive when cranked. THIS was the sound and feel Walrus needed to shoot for in an amp-like pedal. The 385 was developed to have the same simple but effective tone control as it’s grandfather. The amp has this as well but bass and treble are stacked behind the single tone knob. With our design breaking them up, we allow for a much wider array of tones to be achieved. The user is able to boost and cut bass and treble, allowing them to be creative with mid-frequency scoops and bumps. The pedal is internally running at 18v, which helps us nail the same dynamic feel of the amp in a stomp box. This means it is extremely sensitive to how hard you dig in – just like the amp. 

The  Walrus Audio Aetos is an 8-output, isolated power supply, utilizing an internal custom wound toroidal transformer to provide the highest noise filtering and cleanest power, giving artists the purest sound in their signal chain. The Aetos is housed in a solid die cast enclosure and is 4.7”long  x 3.7” wide x 2” height and  has 8 total 9VDC outputs, 6 are 100mA and 2 outputs are high current outputs (300mA)  for higher current drawing pedals like line 6 DL series modelers, the Boss Twin Series Pedals and many digital modulation pedals on the market. It comes with a detachable 120V AC Power cord and also has a 120VAC complimentary power output. This unit comes with 8 – 2.1mm barrel black power cables and 2 black-to-red (Line 6) power cables.  We recommend high profile dual lock for mounting the Phoenix under your board. Fits under most pedal boards including Pedaltrain (PT JR and up), Pedal Pad, Blackbird Boards, Creation Music Company, and Holeyboards.

The ARP-87 is a compact, feature-rich delay, packed with a large pallet of inspirational delay tones. Featuring four main algorithms, digital, analog, lo-fi, and slap back, the ARP-87 can cover some serious ground in the world of echoes. The  Digital algorithm boasts pristine, crystal clear repeats great for rhythmic riffs. The Analog setting works well to add warmth and dimension to chords and lines without getting in the way. The Lo-Fi algorithm, with its adjustable frequency range on the repeats, goes from warm, warped, and murky, to strait AM radio. Finally, the Slap setting makes it easy to dial in a great slap back echo perfect for smoking chicken pickin’ runs. With other features like our smart bypass switching, and momentary knob ramp, the ARP-87 provides endless creative opportunities that are waiting to be explored.   The X knob changes functions depending on which Algorithm you are using. It adjusts a specific parameter in each algorithm. In Digital, Analog, and Slap modes, the knob will control modulation depth. In Lo-fi mode, the knob will control Filter width.  Note that when changing delay types this loads a whole new algorithm and the tempo must be tapped in again. Max delay time is 1000ms. Trails Mode The ARP-87 can be run in trails or no trails mode. In trails mode, when you turn the pedal off, the delay trails die off naturally. In no trails mode, the delay trails are abruptly cut off when you turn the pedal off. To toggle between either mode, hold down the bypass switch for 1 second while applying power to the pedal. Unplug power and repeat to toggle to the other mode. Momentary Functions When the switch is in off position, press and hold the Bypass Switch to temporarily activate the effect to add a moment of delay texture. Releasing the switch turns the effect off. When the effect is on, press and hold the bypass switch to momentarily ramp the X parameter to maximum. Releasing the switch sets the X parameter back to the knob location.  Press and hold the Tap Switch to temporarily ramp the feedback to maximum. Release to set the feedback back to the knob location.

The  Descent was designed to create ambient textures of sound, from thick and endless hall reverbs to symphonic shimmers. The Descent is a three mode reverb system; hall, reverse, and shimmer. In each mode, the user has the ability to feed +1 and -1 octaves into the reverberated signal. The Hall mode will feature a classic reverb sound that can move your signal from a small-room-echo to a haunting long hall- echo. The Reverse mode smoothly flips your signal to playback unique responses and can be manipulated with pre-delay time controls. Shimmer mode highlights the octave features, dry signal, -1, and +1 to mix in your signal and creates a symphony of sound. The Descent offers you eight controls to precisely hone in your perfect reverb. In addition, the user can use an auxiliary momentary switch in the fav input to switch the pedal on/off and/or save presets. If you have an already crowded pedal board, you can set your Descent at the back of the board and run a small SPST switch to the front of the board so you don’t lose valuable real estate. The Fav input requires a TRS cable to be used. The expression pedal control works with most on-the-shelf expression pedals. This feature allows the user to set the high and low parameters of each control and then fade in and out the those controls by moving your foot up or down on the expression pedal.

[em-uh-ser-ee] Anatomy. Sending or coming out, as certain veins that pass through the skull and connect the venous sinuses inside with the veins outside. Built from the ground up, Walrus Audio has developed a new 2-in-1 boost to help make leads stand out, slides sing, finger picking come to life and to push tube amps into great natural breakup. Like the veins its named after, the Emissary Parallel Boost features two independent boost circuits running in parallel to work together to help give your tone a real “sinus clearing experience”. Use one or the other by itself, or mix any combination of both by turning up each knob to the desired level. The top knob controls the volume for the “bright” boost circuit. This is a clean, high headroom JFET boost, with a slight emphasis on higher frequencies to liven up your tone. The bottom knob controls the volume for the “mid” boost circuit. This circuit features a targeted boost at either 1kHz or 800Hz selected by the toggle switch. The bypass switch also features a momentary function. When the bypass switch is in off position, press and hold to temporarily activate the effect. Releasing the switch turns the effect off.
