I started doing some pedal building. I dove in the deep end: Etching, tinning, and doing my own silkscreens with the laser printer; designing my own PCBs in Eagle; every last part needed to build a batch of 5 pedals. So far I've completed a Tonebender Mk2 and I have a Fuzz Face on a breadboard that is sounding great. I've encountered two weird issues that I cannot explain: 1) My Tonebender will not work with the high impedance input on my Vox AC4HW1. Low impedance works great. Tried 2 other amps, works great. High Z input on the Vox = dead silence as if amp input is shorted to ground. It's not the cable! 2) My fuzz face will not work with my homemade power supply. I have a very simple but incredibly useful homemade power supply. It's 8 rechargeable batteries, a LDO regulator to give me 9V, and a typical Boss style barrel power plug. I have used this for years with dozens of different pedals. My breadboarded fuzz face (which has the barrel power receptacle) will work perfectly with a wall-wart, but my power supply will not turn it on. Both these things are real head scratchers (for me anyway). Anyone?
