Hi all,


Is there a way to mod my OTS so that when I engage the OPAB it won't get so "trebly" ? I realle like the sound - it just needs less treble.

I may be wrong - but doesnt the PAB bypass the tonestack?  if thats the case your tone knob on the guitar is your best bet.

you're right - it bypasses the tone stack - I just thought that there must be a way to tweak the amp sp that it is less "trebly"

possibly only bypass the mids and bass, you'll still get a little treble boost due to the mids. when you add mids it adds highs

Listen to any fender, marshall, or dumble tonestack. as you add mids it also raises the highend somewhat. listen to the added brightness you get when you flip the midboost switch

i suggested only bypassing mids and bass(if its even doable) because you will still get a flatter EQ boost which wont sound as trebly

When you put a 8ohm cab on a 4 ohm output tap, the clean PAB isn't boxy anymore.

Wall voltages are not consistent: OTS has a voltage sweet spot on the pre amp plates, once you're voltage gets too low on a bad day, the sound gets: dark, boxy, muddy compressing less headroom etc.

Yep, change the two 22m resistors for 4,7 m types. This reduces the differece between on PAB and PAB mode.

No, as long as your output tap is lower than the Cab's impedance it's fine.
