Gamechanger Audio Bigsby Pedal

The BIGSBY Pedal is a revolutionary polyphonic pitch shifter pedal that is able to reproduce the string bending and vibrato effects produced by the BIGSBY Tremolo arm and other traditional tremolo systems.

Powered by the formidable SHARC® Audio Processor, the BIGSBY Pedal runs a hybrid algorithm specifically developed by Gamechanger Audio to achieve smooth polyphonic real-time pitch-shifting at low intervals. It has been painstakingly tweaked to preserve the natural timbre and sound of electric and acoustic string instruments, including baritone and bass guitars, guitars, mandolins, banjos, etc.

The unique spring-loaded foot-pedal design makes it possible to incorporate pitch-shifting into your playing in new and creative ways. The BIGSBY pedal is always “on” – the only thing you need to do to activate it is to step on the foot-pedal. The algorithm ensures that transitions between the DRY and WET (pitched) signals are as smooth as possible, allowing you to seamlessly incorporate pitch-bends into complex picking patterns as well as lead and melodic lines. This opens the door to a world of new strumming patterns, bend combinations and beautiful lap-steel and slide-inspired licks that cannot be achieved with traditional tremolo systems.

Another key component of the BIGSBY Pedal’s sound is the DETUNE parameter, another carefully crafted algorithm that is designed to emulate the imperfections and dissonant properties of traditional mechanical string-bending hardware. As a result, the vibrato effects produced by the BIGSBY Pedal are almost indistinguishable from those of a conventional tremolo arm.

The BIGSBY Pedal combines the tremolo arm pitch-bend emulation with a unique set of features and modes that can take this pedal much further than simple pitch bend.
- The AUTO mode enables an LFO that controls the pitch while the foot-pedal controls the depth.
- The BLEND control allows for dynamic chorus and harmonizer sounds.
- The external footswitch input makes it possible to use the pedal in latching mode for typical pitch-shifter, octave, detune and chorus functionalities.
- The expression output gives the pedal control over other audio gear, either in conjunction with or separately from pitch-shifting.
- Full MIDI CC and PC control over all parameters, preset recalling, and clock syncing.

- Polyphonic pitch shifting and a reproduction of the BIGSBY tremolo arm string-bending and vibrato effects.
- A spring-loaded rocking foot-pedal for upwards and downwards pitch-bending movements.
- High-quality buffered bypass and seamless transitions into and out of bypass.
- Multi-fuction LED-lit knobs. LED color and intensity are indicators of the selected parameters and values.
- AUTO mode, with an LFO controlling the pitch-bend rate and the foot-pedal controlling pitch bend depth.
- Up to 12 semitone pitch-shifts in both directions. The pitch-bend range can be set separately for both directions.
- Foot-pedal and pitch-shift direction invert switch.
- BLEND control for mixing in the DRY signal to achieve harmonizer or chorus sounds.
- DETUNE control for emulating the tuning instability of hardware tremolo systems.
- Full MIDI PC and CC control over all parameters and extended functionality. A 3.5 mm TRS to 5 pin DIN MIDI adapter is included.
- 10 user preset slots accessible via MIDI PC.
- Expression output for controlling other gear with the spring-loaded dual-direction foot-pedal, with adjustable expression depth and center position offset controls.
- Latching mode is accessible via an external footswitch. The BIGSBY Pedal is compatible with both momentary- and toggle-type footswitches with a TS ¼ inch jack.
- A “KNOB LOCK” option to prevent accidental parameter adjustment during performances.
- Powered by a standard 9V DC center negative power supply with at least 500 mA. Power supply is not included.
