Total Recall Feedback setting

[hjhjazz]

I built a wonderful sounding Total Recall. The Feedback control, however, can only be used in the first quarter of its range. After that it oscillates badly. The distortion of the pedal is a somewhat higher than expected.
What can be wrong? All the voltages check out and the sound with the Feedback control to zero is fine.
Would recalibration solve the early feedback problem?
Anyone?

Sounds like your GAIN1 and GAIN2 could use a tweak, these seemed to have the biggest effect on the usability of the feedback control.

Will try and let you know.
