Mod BYOC Mouse to standard RAT

scabiosa

New member
Dear folks, I made myself a BYOC Mouse a couple of years ago but I like my standard RAT a bit more, so I want to get rid of the Ruetz mod and the presence knob. Can someone help me a bit with what I have to do exactly please?

This is the link to the manual of the BYOC Mouse: https://moodysounds.com/wp-content/uploads/2021/02/mouseinstructions.pdf

Do I only have to unsolder the presence potmeter? On the schematic of BYOC mouse you can see a 0R after the presence potmeter. But I think on my PCB there is the 47R resistor. Or am I wrong?

Looking at the PPCB schematic the 0ohm resistor and Presence pot replace the 47R resistor to the 2µ2 cap. So disconnect the pot and jumper (0ohm resistor) and solder a 47R resistor between the positive side of the 2µ2 cap and pin 2 of the IC. You could connect it at the Distortion pot's lug 2 or 3. Pretty simple.
 
thanks! in my version the 0R is not there (there is a difference between the schematic and the PCB), it is a 47r on my pedal. So with the potmeter on zero, the BYOC Mouse is very close to the original rat isn't it?
 
while your in there it also appears your pots are not insulated and could cause a short to the pcb.. or maybe they are and I cant tell..
