Gamechanger Audio Light Pedal Guitar Effect

Gamechanger Audio Light Pedal Optical Spring Reverb Pedal

The Gamechanger Audio Light Pedal is the world's first analog optical spring reverb system. It pairs a three-spring mechanical reverb tank with infrared optical sensor pairs that capture overtones and harmonics lost by conventional pickups, delivering classic surf-style drip, modulated washes, and self-oscillating drones from one analog signal path.

Infrared Optical Sensor System and Six-Mode FX Engine

Infrared optical sensors positioned along the spring act as photoelectric pickups, unlocking longer decays, subharmonics, and overtones beyond standard transducer capture. The six-mode FX engine splits into optical effects (optics, sweep, trem) and mechanical effects (reflect, feedback, harmonic), stackable for combined textures.

Signal Flow and Connectivity — Mono Reverb Routing

The unit is a true analog mono pedal with a tip-sleeve 6.3 mm jack input and output, plus a separate expression input accepting TS and TRS expression pedals and CV signals up to 3.3 V.

• Input: 6.3 mm TS jack, 1 MΩ impedance — handles passive and active outputs
• Output: 6.3 mm TS jack, 100 Ω impedance — drives long cable runs
• The expression input utilizes a 6.3 mm TS/TRS connection for CV signals up to 3.3 V and can be assigned to CTRL, SPRING, OPTICAL, DRIVE, or GATE parameters.

Controls and Signal Processing — Three Mix Channels and Dynamic Engine

Three mix controls set levels for the dry signal, the classic spring tank output, and the optical reverb signal. A tilt-EQ TONE knob shapes only the wet signal, while DRIVE controls how much signal reaches the spring exciter.

• Mix Controls: Dry, Spring, Optical — independent blend of transducer and optical output
• DRIVE: 0 to max input level — increases spring movement for longer decays
• GATE: dual-function envelope — gates tails or ducks wet signal under dynamics

Power, Build, and Live Performance Features

A shock sensor mutes the wet signal during stomps and stage rattle, with three sensitivity levels. An internal analog buffer preserves signal integrity even when the pedal is bypassed in long cable chains.

• Power Requirements: 9V DC center-negative, 500 mA minimum, 2.1 x 5.5 mm barrel plug
• Peak Power Consumption: 4 W — requires isolated supply with headroom
• Shock Sensor: 3-level accelerometer — silences spring noise from impact
• Buffered Bypass: analog buffer — preserves tone through long cable chains
