Bigsby Polyphonic Pitch Shifter 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 Pedals 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


• Polyphonic pitch shifting and a reproduction of the BIGSBY tremolo arm string bending and vibrato effects
• 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-function 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 1/4 inch jack
• 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

Awesome music shop! Very clean, not crowded. Lots of guitars for everyone's musical taste. The staff is super nice, and very informative. I can't say enough good things about Picker's Alley! Thank you so much for serving Southwestern Ontario with such awesome service!!

Pat P

Great music store. Messaged them about a sale item and they put the last one aside for me until I could get there to purchase.

Tim Clements

Tony is by far the best customer service rep around, He knows his stuff, and is always willing to go above and beyond, I only go to pickers alley, for all my musical needs!!

Ryan Mathews

Excellent service, in one word they know what they are doing just tell them your requirement and budget. Don't worry about price if you see it online it's the same price here in offline too. Best thing is the owner's humour and focus on your requirement more than the sales of the store.

Very very happy and satisfied and will be back for additional requirements.

Adhish Prasai

What a great selection of guitars and amps. Staff is very knowledgeable and friendly. If they don't have what you need chances are they can source it for you. Prices are as competitive as big box music stores so there is no need to look elsewhere. I will continue to support local when I can.
