That's already done - and I'm sure I'm not alone to have built this ! Except the white one because it's a 60s Ge Fuzz. the Black, Green and Red ones are Ge overdrives, on the which the single pot only adjusts the output level. The switches and footswitches are mainly mid-boost or bright-tame options. I could only have put a pot and the usual FSW... But the upper box face would have felt somewhat empty ! I plan to built one though in a 1590A box, standalone with battery, one led, one pot, one FSW on the upper face. I plan... A+!
