Hey Y'all
First: a shoutout to everyone here who has posted before - searching this forum has helped solve numerous issues in the past couple of months as I've (re) picked up a pedal building addiction after a 20-year hiatus.
I've read up on other Caesar Chorus problems and tried a bunch of things but I can't seem to figure this one out.
Clean signal is fine, with the pedal on, and the blend knob all the way to clean - also perfect clean sound. Rate led blinks properly with the rate knob. Switch works to turn on/off the red leds.
However, with the blend all the way to vibrato - nothing. No signal. With my first set of 3207 chips I tried adjusting the trim and at one point got what sounded like the distorted vibrato but then it fizzed out and no signal came back. I switched the trimmer to a multi-turn thinking maybe I could get a "perfect" trimmer placement more easily but that seems to yield the same result: I'll get a distorted vibrato signal for a second then it will get louder and more distorted and then "fizzle" out.
I've tried a bunch of different 3207 chips (some from eBay and even a much more expensive one from GuitarPCB) but it doesn't seem to change it.
Any ideas? I checked my capacitor values (as that's been a problem in the past) and it seems OK.
Thanks in advance.
