I just changed my Celestion Vintage 30 16ohm speaker for a EVM12S 8ohm in my 1x12 OT Combo. My oh my, what a difference! Gone are the ice-picky treble highs, more clarity, more everything. Are there any other simple mods I can do to make the most out of the already great sounding amp? I would love more bottom end, the tone controls aren't very sensitive to an already sensitive amp. STRANGE!! Especially when the PAB is engaged, all the bottom end goes.......

I know that when the PAB is engaged all the tone controls are bypassed, it's a no-brainer. BUT, I was hoping to perhaps change a resitor or capacitor, so that when the PAB IS engaged, there'll be more bottom end to the sound. At the moment, changing from stock OD channel to PAB, the bottom end disapears. Is it something to do with the circuitry? I love the more gainy sound the PAB gives, but the bottom end just goes away......

Would you have a link to your mod described above? I'm finding with my Bluesmaster that the PAB works nicely as a level boost on the clean channel but on the O/D channel it just adds more gain without any perceptible change in level. I'm using a clean boost in the loop (with Klein) to get around this currently.

I guess I should clarify. The mod I have just increases the boost from the PAB and gives more drive. You can get good crunchy OD even on the clean channel with the pre volume set at noon with the mega PAB engaged.
