Okay, so I have checked all the values in the LFO and they are fine. I havent substituted any parts. I have a hunch that the capacitance of the probe is changing the behavior of the circuit. The probe has a 10m input impedence and a ~13pf capacitance.

Tech Help - Projects Page / Pork Barrel only works with oscillioscope probe....
June 10, 2016, 05:26:47 AM
Hi all
Just finished building a pork barrel, and I have a very peculiar issue...
The LFO works (up until the depth pot) and the audio path works (checked on my scope). However, I get no chorusing effect unless I place my scope probe on the junction of D1 and D2. When I attach my scope to this junction the effect works fine, but without my probe connected, I just get clean audio straight through the whole effect!
Any ideas?
