I picked up a vox wah for about $20 off Reverb that was known to be crackly. I’m not a big wah user but I like the parked sound combined with fuzz so I gutted it and crammed it into a standard pedal enclosure. I only had to rewire the pot and power supply. Once I clipped the zip tie for the wiring harness I was able to get the jacks and switch into predrilled holes from another project I never finish. A little double-sided tape on the bottom of the pcb to keep it from shorting out and I was able to jam the board in there under the jack and it’s nice and snug. Won’t be able to squeeze a battery in there.
