Gamechanger Audio Bigsby Polyphonic Pitch-shifter Pedal

The Gamechanger Audio Bigsby Pedal is a high-end polyphonic pitch-shifting stompbox inspired by the iconic vibrato arm systems of classic electric guitars. Underneath its mechanical foot-pedal design lies advanced digital processing capable of smooth real-time pitch shifts, harmonization, and expressive modulation. It blends vintage feel and modern capability offering musicians a creative pitch-bending tool that extends far beyond traditional tremolo or vibrato effects.

Specifications & Features:

• Polyphonic pitch shifting up to ±12 semitones (i.e., a full octave up or down) in both directions.

• Foot-pedal design: spring-loaded rocker bar mimics the feel of a Bigsby vibrato arm for hands-free expressive control.

• Blend control allowing mix of dry and wet (pitched) signals, enabling harmonizer and chorus-style effects.

• Rate control: when set to zero the pedal responds strictly to foot-movement; when increased it enters “Auto Mode” with internal LFO controlling pitch bend rate.

• Detune control: simulates the slight instability of mechanical vibrato systems for authentic vintage character.

• Tone control: adjusts brightness of the shifted (wet) signal independently of the dry signal.

• Expression output / footswitch input: can be used as an external expression controller or external footswitching of latching modes.

• MIDI input (3.5 mm TRS Type B) for preset recall (10 user-slots) and synchronization of Auto Mode to external clock.

• Input impedance: 1 MΩ; Output impedance: ~100 Ω.

• Frequency response: 20 Hz to 20 kHz (±1 dB); Signal-to-Noise Ratio: ~90 dB (A-weighted).

• Power: 9 V DC (center-negative), minimum ~220 mA. Dimensions approx. 220 × 110 × 86 mm (8.6″ × 4.3″ × 3.3″), weight ~0.96 kg (2.11 lb).

• True or buffered bypass? (Mostly buffered given the complexity of the tracking circuitry).

Why You’ll Want It:
If you’re looking for more than a standard pitch shifter or tremolo effect, the Bigsby offers expressive terrain from subtle vibrato to full-on polyphonic shifts and harmonies. Its combination of foot-pedal interface and advanced processing makes it ideal for creative guitarists, experimental players, and anyone who wants to push pitch-based effects into new territory—especially in live or studio settings where expressive foot control matters.
