Long time lurker... Here's a DIY build of the Super Champ XD Footswitch. Turns out the appropriate footswitch for the SCXD is hard to come by and on backorder everywhere you look. You can't use standard Fender 2 Button footswitches, as they only change between channels and do not toggle the on-board effects... something to do with the SCXD looking for a voltage drop, not just the opening and closing of a circuit, for the effects toggle. Anyway, I used the schematic I got off of the Fender Discussion Forum and sourced the parts at Radio Shack and spent ~$16.00: 2750011 SPST Push On/Off Switch - 2 @ $1.99 2760068 RED LED Light (2 per pack)- $2.49 2740252 2 Pack 1/4" Mono Jack - $2.99 2760565 1n4733 5.1v Zener Diodes - $1.39 2761102 1n4003 Silcone Diodes - $0.99 2701805 Project Box 6x3x2 - $3.79 Simple Build... kind of tricky getting it into the enclosure. Works Great!
