WHAT IS THE MOTOR PEDAL?

The MOTOR Pedal is a fully playable electro-mechanical synth voice THAT TRACKS THE pitch of your playing in real time.

YOU CAN PLAY IT AS A melodic DOUBLER OR HARMONY CREATOR, use IT AS A POWERFUL and versatile DRONE GENERATOR, or distort & process your instrument with the x-mod & vocoder engines.

This isn’t an emulation.
This isn’t analog modeling.
This is the raw sound of a brushed DC motor, pushed to the edge and tamed with precision control.

HOW IT WORKS

THE MOTOR PEDAL USES A REAL-TIME PITCH TRACKER TO ANALYZE Your INSTRUMENT'S OUTPUT

WHETHER YOU ARE USING A GUITAR, A BASS, OR A MICROPHONE - THE motor's rotational speed WILL BE PRECISELY MATCHED to THE FUNDAMENTAL FREQUENCY THAT YOU ARE PLAYING

FOR EXAMPLE - TO MATCH A 440HZ INPUT THE MOTOR WILL HAVE TO ROTATE AT
146 REVOLUTIONS PER SECOND

A carefully calibrated inductor captures the real-world motion of the motor’s spinning coils—transforming mechanical energy into a raw, electric audio signal.

FIVE MOTOR-BASED
SYNTHESIS ENGINES

The MOTOR Pedal features five unique and powerful sound engines based on the motor core:

MOTOR - Raw electromagnetic pickup of the spinning coils. Glitchy, growling, magnetic.

MXD - Cross-modulation of the motor with a digital waveform. creates HARSH, DISTORTED AND METALLIc textures.

M-WAVE - A digital oscillator that's PITCH-LOCKED & HARD-SYNCED to the motor's output.
a multitimbral synth with aN IMPERFECT mechanical soul.

COIL MODE - instead of spinning the motor with DC Voltage - We inject alternating current into the motor's coils to create resonant analog vibrations & metallic hums.
THIS IS AN INNOVATIVE SYNTHESIS METHOD THAT SOUNDS LIKE NOSTALGIA ON STEROIDS.

VOCODER MODE - A 24 BAND DIGITAL VOCODER THAT USES THE MOTOR'S OUTPUT AS THE CARRIER AND Your instrument's signal AS the modulator.

Speak, sing, or shred DIRECTLY through the machine.

PARAMETER CONTROL

Analog TONE BOOST – A POWERFUL TILT EQ FOR SHAPING THE MOTOR OUTPUT

TWO VOLUME KNOBS - independent Volume control for DRY SIGNAL and MOTOR OUTPUt

motor drive – heavy analog distortion for the motor output

Envelope – go from short, punctuated stabs - to envelope follower - to long releases

glide – applies a portamento curve to the motor engine

vibrato – classic pitch modulation - from subtle movement to wild oscillation

motor Interval Selector - ALLOWS YOU TO OFFSET THE motor pitch: +/- 1 octave or perfect fifths or perfect fourths

X-MOD Mode – use Amplitude modulation to Cross-mod the input signal with all motor engines.

STEP ON THE GAS

the MOTOR Pedal COMES EQUIPPED with a MULTI-MODE GAS pedaL

ACCELERATOR - create a wide range of controlled pitch-shift or floor it to redline the motor

BRAKE - downward pitch-shift, or mash the pedal to bring the motor to a stall

CLUTCH - temporarily disconnect the motor from the pitch-tracker - perfect for creating drones

VOLUME - use the spring-loaded pedal to CREATE satisfying volume swells

DRIFT - play the pedal like a gentle vibrato arm, or just floor it to get a complete wipe-out

DURABILITY

THE MOTOR PEDAL USES A SPECIALLY-DESIGNED BRUSHED DC ELECTRO-MOTOR BLOCK AS ITS CORE SOUND ENGINE.

OVER TIME THE MOTOR'S BRUSHES ARE GOING TO erode AND THE MOTOR block WILL NEED TO BE REPLACED - INDICATED BY THE PEDAL'S CHECK ENGINE LIGHT TURNING ORANGE AND THEN RED

THE MOTOR block IS A REPLACEABLE PART

ESTIMATED LIFESPAN AROUND 3000 - 5000 hours of intensive PLAYING

INSTALLING A REPLACEMENT MOTOR FROM GCA IS A BREEZE
COMPARABLE TO CHANGING A SET OF TUBES IN YOUR AMP.

the MOTOR REPLACEMENT PROCEDURE IS extremely SIMPLE AND DOES NOT REQUIRE PROFESSIONAL SERVICING.

FREQUENTLY ASKED QUESTIONS

Definitely! The Gamechanger Audio MOTOR PEDAL tracks any monophonic source with any instrument - electric guitar, bass, synths, or microphones. If your instrument produces pitch, the MOTOR of the MOTOR PEDAL can follow it.

The MOTOR PEDAL analyzes your input in real time and adjusts the MOTOR's rotational speed to match the fundamental frequency you’re playing. For example, a 440 Hz note spins the motor at 146 revolutions per second. The pickup and sensors read that motion three times per rotation. The result is fast, stable tracking that still preserves the beautifully imperfect behavior of analog hardware.

That depends on how you use it. At its core, the MOTOR PEDAL can be a thick, glitchy synth drone, a harmonic doubler, a ring-mod or cross-mod monster, a metallic, resonant noise engine, or a mechanical vocoder. It can whisper, growl, scream, shimmer, and collapse - often all within a single phrase.

The MOTOR PEDAL features a mono MAIN IN for instruments, a TRACK IN for pitch tracking, a MAIN OUT (wet + dry), a TRACK OUT (unaffected tracked signal), MIDI IN, and a DC power input (center-negative 9–12 V with a minimum of 500 mA). Connect USB-C for firmware updates, diagnostics, and MIDI over USB.

Yes, the MOTOR PEDAL includes a 5-pin MIDI DIN cable input, as well as USB-C for MIDI and firmware updates. You can control pitch, parameters, and integration with external gear or DAWs.

Experimental musicians, sound designers, guitarists bored of “more gain,” synth players craving tactility, and artists who want instruments, not presets. If you like your gear to fight back a little, you'll feel right at home.

MOTOR PEDAL includes five radically different synthesis engines, all derived from the same physical motor:

MOTOR - raw electromagnetic pickup of the spinning coils, which are glitchy, aggressive, and alive.

MXD - cross-modulation between the motor and a digital waveform, delivering harsh, distorted, metallic textures.

M-WAVE - a pitch-locked digital oscillator hard-synced to the motor; a multitimbral synth with a mechanical soul.

COIL MODE - alternating current injected directly into the motor coils, producing resonant hums, analog vibration, and nostalgic industrial tones.

VOCODER - a 24-band digital vocoder using the motor as the carrier. Speak, sing, or shred directly through the machine.

No, the MOTOR PEDAL is not stereo; it operates as mono in / mono out.

The built-in spring-loaded expression pedal is not an afterthought; it’s an instrument that features normal and “floor-it” ranges with five selectable modes: Accelerate, Brake, Clutch, Drift, and Volume. You don’t just control parameters - you drive the MOTOR with the MOTOR PEDAL.

Absolutely, the analog hard-clipping MOTOR PEDAL Drive Analog tilt EQ (±6 dB at 300 Hz) ensures that everything stays punchy, musical, and responsive.

Yes, the MOTOR PEDAL Interval Selector allows pitch offsets: ±1 octave, perfect fourths, perfect fifths for instant harmonies, drones, and alien counterpoint.

Yes, the MOTOR PEDAL includes two independent volume controls: one for the clean signal and one for the motor output. You can layer, balance, or completely replace your original tone.

X-MOD uses analog amplitude modulation to cross-modulate your input signal with any motor engine. The result: ring-mod textures, sideband chaos, and brutal harmonic complexity. This is where the MOTOR becomes truly unhinged in the best way.

They let you separate pitch tracking from audio processing. You can track pitch from one signal or process a completely different signal - opening up advanced routing for studio tricks and modular-style workflows.

Yes, and intentionally so. The brushed DC motor is a real mechanical component. Over time, its brushes will wear down; the expected lifespan is 3,000–5,000 hours of intensive use. This is indicated by a check-engine light: orange indicates approaching replacement, and red means it’s time to swap the motor part.

Not at all! Replacing the motor block is comparable to changing tubes in a tube amplifier.

No, the MOTOR PEDAL does not include a power supply. It requires a center-negative 9–12 V DC supply with at least 500 mA. Do not use an 18‑volt power source!

There are no options to insert batteries.
