I was cleaning & fixing up my old GT-3 today, and i was wondering how well this would work without scrapping the good old '3'.
For the foot switches, i'd simply solder some leads from the 1 2 3 4 switches. You just need a ground wire and one wire for each footswitch.
For the exp. pedal, it's almost as simple: there's a tiny circuitboard under it with a stacked potentiometer controlled mechanically by the pedal, this pcb has a 3-lead cable connecting it to the main board, one red and two white. You just need to connect these 3 leads to a 1/4" stereo jack. Red goes to sleeve (ground), middle white one goes to ring (right channel), and the other white one goes to the tip (left channel).
Now i just need to find out if this will work with the pedals still part of the GT-3.
