I recently bought a cheap dual footswitch pedal for my marshall.
Turns out, the channel switching works but turning the reverb on and off didn't. Seems like the wires are differently connected to the jack than the real marshall footswitch.
Managed to fix my original marshall footswitch.

So I have a dual footswitch with LEDs that won't be used, any ideas how it still might be useful, or should just try and sell it?
I think you can use switches for some effects pedals, like using a tap tempo for a delay pedal and such. Dunno about anything else tho...
Joža je kul. On ma sirove z dodatki pa hambije.
use the switches and housing and build some kind of effects pedal.
