I have a marshall footswitch for my MG and just wondered if it would work if I plugged it into my JCM?

If not, where could I get a footswitch for my JCM? Or could I get something that would do the job?

Also, do I just need instrument cable for an effects loop?

The footswitch should work. For the effects loop you just need one cable infront of the effect and one after. If you have multiple effects you need patchcables between aswell...
