This might sound like a stupid question but can you use any chanel pedal on any amp?

I just got rid of my Marshall MG50 and am waiting for my Orange Crush to arrive, will my Marshall pedal work on it? Or will I need an Orange one
Well all footswitch pedals are the same to be honest. If the Crush has a footswitch there's a 70% chance it'll work.
Yeah most likely it will. There are some differencs (how many buttons and therefore how many diffrent things you can change). Alos many pedals use different jacks. But there is no problem in trying.

I noticed the Crush has one button and the MG has two. One of them might work but don't be sure it will be the Channel button on the Marshall FS, it could be the DFX one
