What you'll need:
- ) Soldering iron & solder (optional: Heat shrink)
- ) Hand drill/Drill press
- ) 2x Single Pole, Double Throw (SPDT) *Momentary* stomp switches. Make sure these have the solder lugs like the ones pictured, not the PCB board pins or you're going to have a hard time soldering wire to them.
- ) 1x Stereo 1/4" jack.
- ) 4x pieces of wire, cut to desired length.
- ) And lastly, a pedal enclosure (mine is an unpainted 1590bb).
I already had everything except for the switches, jack and pedal enclosure, which I paid less than $20 for. Could have been even cheaper if I'd have searched around for a single stereo jack, but the place I ordered from only had a 3-pack for $2.99.
Ok, so, plot out and drill your holes in your pedal (You can find better directions for this on YouTube than I can give).
And then follow my schematic to wire it up. Be sure to pay close attention to my highly detailed wiring schematic, here. It can get confusing.
And here are the innards of my final product. I like to use a little extra wire than needed for play in case I want to move/add/replace something later on down the road. I also like to keep the solder joints nice and tidy with a bit of heat shrink, especially inside a metal case where something could potentially cause a short. (Tip: If you're going to use heat shrink, save heating all of them until last with a heat gun to avoid accidentally shrinking one that wasn't in place. This is a tight space.)
Now, go into the User options via the editor, or the unit, select "Foot Switches" and change both A and B function to "Prev Rig" and "Next Rig" respectively. There are other things in those drop-down lists that the pedal may work on engaging, but I can't say with 100% assurance. Because I only needed/wanted it for channel switching. So, try others out for yourself.
And here is a gif of it working.
As you can see, I don't particularly care what mine looks like at the moment. But you can order the enclosures pre-painted, or paint it yourself. It's up to you.
