Howdy everyone, I'm a new user to this forum. I've build a couple dozen pedals and this one has me stumped. It's the AION TriVibe. All spec parts, I get power. I get sound both in bypass and on, I do not get modulation in any setting. The volume is about the same either way. I followed the audio signal path through the circuit and it is where it should be. I've swapped out the 13700 with a known working one with no additional changes. I've reflowed and reflowed. If anyone has any suggestions, or thoughts it would be appreciated.
