My Pot Problem ...

[Structo]

No but my local place has some nice PEC pots.
But all they have is linear.

Spendy at $10.50 each....

But they sure are high quality, sealed pots.

After playing the amp for a few days I've concluded that the P.E.C removes some of the harmonic overtones, also, gives the amp more room before it breaks up. LOUD!
If I had a vintage amp I'd probably stick with a Fender spec to achieve that mojo. However, I like the way this amp comes over ... it fits my playing style.
Meanwhile, I'm waiting for my sluggish CNC guy to finish the aluminum trim panel so I can put in the 8" Tone Tubby.

Cheers!
