I’ve had the same issue with a number of Kliche builds. What makes me think that it’s not the Charge pump is, I built a bunch of Aion Klons which also have the 1044CPA chip and I don’t hear the high whistle on those. The problem is very obvious when I use the half speed button on my looper pedal...
I had a chance to try another 2n6027 and that didn't make a difference. I'll don't think my voltages are correct and will double-check my resistor values again.
I'm looking for some help with the Woodpecker Tremolo board. I've checked it over multiple times and the resistor values seem to all be correct. Could someone please look it over and maybe compare voltages on their own 'working' Woodpecker? Mine has the original signal but no effect. Here's some...
I've had a bit of time to play through the Nucleus and don't think it's functioning properly quite yet. The sound is fuzzy and loose and not at all like the demos I've heard of the Atomic Overdrive, which has more of a hot-rodded Marshall tight distortion sound. I've probed around the circuit...
I checked the voltages on the TL072 opamp:
pin 5: 0.37v
pin 6: 3.02v
pin 7: 8.49v
pin 8: 9.13v
I don't seem to have continuity between pin 7 and ground. Are you sure that's necessary? the schematic doesn't seem to show that. thanks for helping out.
I need some help with this pedal, I've made 5 in a row without any problems but this one has me stumped. The signal sounds great right up until the end of the circuit and then gets really quiet and noisy (ground hum). Here's a gut shot and where I believe the problem is in the schematic. I've...
