This is a timely thread.  I just put away an OCD build.  Why?  It squealed at max gain and I couldn't figure out how to get rid of the squeal except to reduce the gain pot (or up the capacitors in the first op amp feedback network).  But then the circuit just sounded ordinary and uninspiring at lower gain.  I didn't think to try a buffered pedal before the effect.  I have Boss TU-2 tuner that can supply buffered output for testing.  Something to try...
