I built a Pendulum, tried it out briefly before boxing it up, and it seemed to have a very nice, almost Univibe-y sound. I initially had the wrong value pot for the speed control, and I think I may have damaged something either changing the pot or putting the board in the enclosure. It now sounds like a very plain trem with all the high end removed. The high pass and low pass LEDs blink in an alternating fashion, and the rate indicator LED seems like it does what it's supposed to do. I replaced the high pass LED and the LDR (I used the Tayda ones) and the electrolytic next to them (C101), and swapped the two ICs around, but the sound didn't change. Have looked at the back of the board for solder bridges or misc debris and didn't see anything. Can someone advise how to troubleshoot this; specifically, how to tell if the higher frequencies are being lost at some point?
