You can also reduce the preamp gain. You could try dropping the V2 plate resistor from 100K to 82K and see where that puts your voltage and sound.
1. This is not a F*nder, and it's not supposed to be that clean. Your demos started off sounding very clean to me, with excellent tone. I wouldn't change it personally.
2. This is a touch-sensitive amp. You can play lighter, or roll off the guitar volume a little bit to clean up the amp. And you can turn up the guitar volume or play harder to get more dirt. I'd experiment with this before you do anything else. And post a demo of doing this. - no pedals, no touching the amp, just adjust the guitar volume knob and see what happens.
Well to try the plate resistor... it's very tight to try that without burning caps.
Is there any harm in placing a parallel resitor of 470K ..the total resitance is normally around 82K then?
In fact..I have the cap to ground on the spot of the initial schematic, right next to the phase inverter area.
