Title: overtone hrm internal pots Post by: jubeman on June 24, 2009, 07:37:24 PM quick question
can someone tell lme what the three internal pots on the hrm internal board do and how they interact with the front tone controls as there seems to be so many ways to set this amp up any advice appreciated derek Title: Re: overtone hrm internal pots Post by: JD0x0 on June 24, 2009, 08:26:18 PM Three of the trimpots are used for treble middle and bass on the OD channel. there should be three other trimpots like on the non-HRM one is the OD trimpot, the other is the phase inverter bias and the last is the FET(i believe its not on the HRM)

Thanks for your reply . but which pot is which ? 250k, 1meg ,20k and are they only on when PAB is on ?? thanks Title: Re: overtone hrm internal pots Post by: JD0x0 on June 26, 2009, 07:23:41 PM no the PAB bypasses the tonestack on the clean channel for a boost on either channel. looking at most amps im guessing the 250K is treble, 1Meg is bass, and 20K is midrange.
