Here’s a quick look at converting a stompbox effect into a Eurorack module.
The video, via LeoMakes, assumes that you’re starting from a working guitar pedal board that runs on a 9 volt battery, and that you want to run it on standard Eurorack power.

- 0:38 – The plan
- 4:49 – The build
- 8:01 – Hear it in action
His previous video, embedded below, covers the build of the actual distortion pedal board.
Cool sound but isn’t the Rat intended for instrument level signals? Sometimes it’s fun to plug a synth straight into a pedal but it’s never ideal. I wouldn’t want a module that doesn’t match the impedance of everything else in my system.
since there is a mini pcb needed for the violate regulator ( btw i would spend a head sink just in case the existing effect is hungry for current) a simple input and output opa to just voltage and impenitence should be not the problem.. if u do both input and output as simple as possible with a simple sum schematic there will also no phase shift just in cased…at least i would do it that way … i’m not sure to buy the new ocean 11 reverb and put it in to my euro rack that way … with used gear its not a problem just open a fresh new device is hard for me 😉
you can run a RAT at +15v – no need for a 9v regulator – some pedals use a charge pump to get +/- 12 or higher to get more headroom…also, if you are concerned about feeding higher levels to the pedal just attenuate the input with a potentiometer
Should’ve called it the “EuroRat”.
Any chance you could elaborate a bit more on the power conversion?
Currently working on a project to convert a EHX Clone Theory to Eurorack, and managed to get a decent sound by replacing the 9V battery adapter with a JST connection into Eurorack rack power supply on +12v and Ground, via a buck converter.
There footswitch is still attached though, and I’m unsure how to get rid of that whilst still retaining power? My idea is to use the current power connection I’ve hobbled but in the place where the DC in power jack is?
