Okay – here’s where I’m at: Working through #6 everything was checking out until I started checking voltages on the IC. Several voltages were way off. I dont really know how the pins are labeled, so bear with me as I try and describe it. Most pins register about 4.2V unless otherwise noted. If you are looking straight down on the board (so the IC is upside down) – pins from left to right, top row: pin #3 reads 2V, pin #4 reads 8.32V. Bottom row, left to right (again, IC is upside down) pin #3 reads 4V, pin #4 reads 0V. Reading voltages at resistor R10: left side reads 4.04V, right side reads 8.33V, so I think that resistor is working. I went over all the parts listed in Appendix B (U2 Voltages) just in case. I cant see any bridging or bad joints, but after re-flowing the solder a bit earlier I may have burnt a pad. Anyways, since I don’t know what parts those pins affect, any guidance would be appreciated. I worked through the rest of #6 in the Troubleshooting manual as well. So I had re-done the jumpers too (that seems to be a common error part) and re-flowed some other joints as well. After testing, pedal still functions the same (everything works, but volume is still low).
