Boss GP-10 Mod

Because I don't use footswitches on GP to change patches I'v look for some "usefull" usage of those two footswitches... By looking on board I found that those two switches isn't in "matrix" but just connecting wire from mainboard to ground.. I just cut apropiate wires, add DPDT switch to be able to set it to normal function and attach 3,5mm jack... now those switches operate as "external" footswitch :-)

(I'll provide wiring diagram later)

Now by connecting new 3,5mm jack with CTL3/CTL4 input I can use "down"/"up" footswitches as CTL3/CTL4...
