Gamechanger Audio Bigsby Pedal guitar pitch shifter pedal. The BIGSBY pedal is a revolutionary polyphonic pitch shifter that reproduces the string bending and vibrato effects produced by the BIGSBY Tremolo and other traditional tremolo systems. The idea of creating a BIGSBY-style pitch shifter was born from an admiration for the unique feel, sound, and design of the BIGSBY system.

Powered by the formidable SHARC® audio processor, the BIGSBY pedal runs a hybrid algorithm developed specifically by Gamechanger Audio to achieve smooth real-time polyphonic pitch shifts at low intervals. It has been meticulously tuned to preserve the natural timbre and sound of electric and acoustic string instruments, including basses and baritones, guitars, mandolins, banjos, etc.

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 pedal's exclusive spring design opens up a world of new strumming patterns, curve combinations, and beautiful lap-steel and slide-inspired licks that cannot be achieved with traditional tremolo systems. The BIGSBY pedal is always "on": all you have to do to activate it is step on the pedal. The algorithm ensures that the transitions between the Dry and Wet (tone) signals are as smooth as possible, allowing you to seamlessly incorporate pitch inflections into complex picking patterns, as well as lead and melodic lines.
