beaurawls said:The self feedback or squealing with no input is common in early Boogies. This I confirmed with Mike B. yeserday. Normally the onset of this is at high ie. 5-9, settings. This can change drastically with different 12AX7's. Have high quality spares and experiment. The stereo footswitch jacks on the chassis can give symptoms similiar if they are oxidized. This is a common problem as they are old and seldom used.
thanks man, do you think the ISP pedal would fix that?
