This is my PCB for runoffgroove’s Umble overdrive.
The circuit has been altered to have less gain. The original had way too much for my liking.
Listen to the soundfiles!
The Umble is modelled after one of the famous Dumble amps.
Board mounted pots can be used to make the build easier.
Version 1.3 of the PCB has an optimized layout and testpoints for easy biasing of the circuit.
