Deathklaw problems

[mightyshocks]

From another thread:

Oddly enough, having this same problem [as the Aquaboy] with the Deathklaw. It goes into self-oscillation with Feedback at only 1/8 the way up (!), with very filtered sounding repeats as opposed to progressively filtered repeats. I checked my values and they seem ok. Is there a specific component that may be the culprit?
