Here I choosed a couple of Fender pedals (footswitches for Fender amplifiers), because I got two (for free) that did not belong to any of the amps in the musicstore I work in. Actually a very good choice since it is very easy to modify these pedals and they are very sturdy. I had the luck to get my hands on two fourwayswitch pedals, but this mod apply to any of Fender footswitches (not those old egg models though!). These pedals exists in models from 1 switch up to 4 switches as far as I know (never seen five but maybe that exists too?). So you have the option to go a bit smaller if you want to by choosing perhaps two threewayswitches or one threeway and one fourway.
Start with demounting one of the black plastic sidepanels (which is mounted by four screws). The switches themselves are mounted on a steelpanel which you can slide in/out. You decide for yourself if you want to reuse this panel (you can flip it upside down if you don´t want that text visible). My choice fell on making my own panel since I´m going to mount two pedals together.
