Im playing a gig in which ive borrowed a peavey valve king combo, but theres no footswitch.

I have a marshall channel selector, which is all i want, to swtich between clean and distortion.

this amp has clean and distortion channels, but it has a gain boost button and when i plug my marshall footswitch in it only selects between distortion and gain boost.

I am very confused about this.

anyone know anything about this?

cheers in advance

Different footswitches are wired to have the ring and tip of the plug control different things so not all footswitches are compatible/interchangeable with all amps.
