Building a
Mid-fi Demo Tape fuzz today, and I get no fuzz. I've tried with a good JRC4558 and a TL072 (both pulled from verified working builds) and I get nothing but hum.
I've X-acto'ed the grooves, checked continuity across the tracks, checked the components, reflowed my solder joints, etc. And still nothing.
Voltages (from the TL072)
1 - 7.76
2 - 1.5
3 - 4.25
4 - 0
5 - 6.29
6 - 8.5
7 - 1.37
8 - 8.5
