Default Re: Growling, howling, shrieking guitar amp

Hi Steve, not familiar with this amp, some pics would be nice. Its obviously oscillating, and I would say probably something in the pre-amp/tone control area. Im presuming its a valve amp so check coupling capacitors and cathode bypass capacitors.
