Electro-Harmonix Signal Pad
Electro-Harmonix · pedal
The Electro-Harmonix Signal Pad is a fully passive, true bypass signal attenuator pedal. A single Level knob cuts guitar output from unity to silence. It requires no power — no battery, no power adapter — and the passive resistive circuit adds no coloration at moderate attenuation levels. Common applications include reducing overdrive or distortion output to match unity gain, or switching between a boosted lead level and a lower rhythm level without touching the amplifier. Discontinued in 2025.
