I know people have been messing with these for a while.
I was pretty unimpressed with the factory tone and have given these a PASS....
Until I took a look at the schematic and realized that they are basically a tweed champ with a pair of 1 meg resistors in the middle in a network to kill the gain,
one goes to ground and one adds series resistance between the stages
So I Picked on up and made it a CHAMP
I asked a buddy for his opinion and he kept the amp ...
the thing sounds that good
here's the mod clip
