Modern low-noise distortion effect pedal for electric guitar. This pedal provides adjustable gain, tone, and volume control with relay true bypass and soft-touch footswitch operation. The design includes LED status indication, anti-pop mute switching, reverse polarity protection, and separated analog and digital power sections for improved stability and reduced noise. The project uses an ATtiny412 tinyAVR 1-series microcontroller for control logic, a TPS70950 voltage regulator for the digital supply, OPA1656 audio op-amps for the analog signal path, a G6K-2F-Y-DC5 relay for bypass switching, a TLP3431 photorelay for anti-pop mute control, and BAS16 diodes for symmetrical clipping.
