I have a odb3, sd1 and oc3 and I like them all but I would like to know if there's any additional sounds I might be able to get out of them. I've seen permanent mods from JHS and analog man but I'm not looking to permanently change the pedal, just a toggle switch on the face of the pedal for a boost or cut or what have you. Seems like there should be some for the sd1 at the very least but I could be wrong.
The thing is that most mods involve swapping out more than one component, in more than one location on the circuitboard. So there's no easy way to put "the mod" on one wire to a switch. There are few exceptions, where the mod is just one component or like one pair of diodes. In those cases it would be easy enough.
Check out monte allums mods, many options including mod bypass in some cases Not all your pedals have mods but maybe some
