I recently acquired a TSL 100 head, but no footswitch. I see some 5 channel TSL footswitches on sale for over $130. I was just wondering if there was another cheaper Marshall footswitch that was compatible with the TSL? All I care about is being able to switch the clean and overdrive channels, the reverb or FX I could care less about. Or if there was a way to convert from a quarter inch input, to whatever input is used for the TSL, and still have the pedal function. For example, I have a valvestate footswitch that is just clean and overdrive 1/2 with a quarter inch input. Is there a type of converter that would work?

Any information would be helpful, thanks!
