This knobless module is split into two parts. The guitar to synth section is a simple boost. The synth to FX section is a buffered attenuator which brings synth level (12V max) down to something resonable for guitar effects.
It is originally based on AI Synthesis' Stomp Adapter module.
I try to post some test results later, but this is it for now! This design can be modded to add pots to increase gain or attenuation.
Let me know if you’ve built it. Tag me on Instagram @benjiaomodular.
