How to add darkness to a Brighter Jmp Cameron Aldrich?

[Mesa\Kramer]

Too bright even with the Treble and Presence on zero?

Other things to try:

Greenbacks
JJ Power Tubes
EQ in front or in loop
300k pots in guitar

Ok this is what I got.

With Gary help and instructions I finally took off goop of V1. He had the idea that something was wrong with the preamp circuit since I was not getting as much gain as an Aldrich has to have.

Behind goop I've found that one pin of V1 was kinda burned or like a spark was there. I have replace the socked and soldered all on its place carefully.

The amp is working great now. Amazing amount of gain and great punch and low end!

But was still too bright, specially at high notes.

So Gary suggested me to replace the original 68k resistor between input and v1. I replaced it for a 100k and now I'm happy with it.

Thanks you so much for all help specially to Gary which had lt of patience
!!
