the PAB is a little too much for my way of playing
can it be trimmed back? I saw no trimmer for this

I have another amp with PAB added, and the footswitch has a pot on it to set the PAB gain level

thanks

68k resistor going from mid pot to ground determines your PAB level.

bigger resistor = more gain

the original Bluesmaster amps have 22M in there and it's called MEGA boost  Grin

just decrease that value or use 100K pot for fine tuning

That would be a linear pot I assume?
