I attempted the Moodring for my first build - probably should have started simpler, but I'm already this far now, so no going back. I have everything hooked up, and I can pass a good clean dry signal through it. However, whenever I add in the "mood" knob, I get this awful reverberated buzz sound. Additionally, when I test my IC voltages, I am almost dead on everywhere. The places with wrong IC voltages are:
IC1: pin 2 (4.2V instead of 4.54V)
IC3: pin 7 (0.52V instead of 0.69V)
IC4: pin 3 (2.24V instead of 4.13V), pin 5 (2.24V instead of 4.13V)
I've checked every resistor and have found them all to be of proper value. Any thoughts?
You did have the BTDR-2 in there when you tested it?
Yes. Just removed it to ensure all connections looked good underneath.
Cool, just checking. I'd recommend you upload some larger pictures.
Is anything making contact with the back of the potentiometers?
