This is a true-bypass relay bypass kit for your DIY pedals. It has EQD-style hold functionality, optional optocoupler muting, and more.

See more details here: https://mas-effects.com/relay-bypass/

Base price includes PCB with pre-assembled SMD components, and a pre-programmed ATtiny microcontroller (IC).

For a few dollars more you can add the rest of the parts to build this (note the first two may be hard to find):

  • Relay
  • Optocoupler
  • Voltage regulator
  • Capacitor

Build docs here: https://mas-effects.com/relay.pdf

You can find a cheaper PCB+IC combo for earlier versions (v1, v2) here. Complete kits for v1 and v2 are sold out though.
