Hey all - This one goes out to the pedal tinkerers: how can I mod a pedal to have an expression pedal input? What parameters are most easily modded in this way? My case is looking into getting a Fuzzrocious Grey Stache but with a modded blend knob with an expression control, which Ryan has said yes to the blend but no to the expression. I had a similar question go out to Ryan of Dr Scientist, who said in his particular case (question about a gate) it would involve some heavy PCB redesign. I've got a Grey Stache Plus I love (it's up for trade/sale because of the reason I'm about to describe), but I use a Barge Concepts Blender to control the wet/dry blend so the dirt fades in and out nicely, and the Barge Blender has an expression out.. But I'd love to compress this 2-pedal setup and get something more compact. How easy would it be to mod the Stache I've got or get a new one (the Plus' boost footswitch I hardly ever use and would rather recover some board space)? I'm thinking new Stache, which would cut down on the floor space, but if I can't install an exp. out, it doesn't help me eliminate the Blender. (Which works brilliantly, but it's just bulky/heavy/a hassle with power supply setup, etc.) I seem to be bothering a lot of builders these days with requests which are generally impossible, possibly due to lack of space in enclosures, but having so little electrical experience doesn't help.
