Hi Folks just wondering if someone could throw some tips for making some more advanced changes to the amp block. I'm trying to nail down Tool tones and a big part of that is a heavily modified Marshall.

Here's the info on the mods done

It's a 1959 late 70s superbass with jj el34s and chinese preamp tubes. It is super lead spec w/ 100k feedback on the 4 ohm tap it has a .68 cap for the presence and a .68 for v2 also the caps out of v1 are both .022s. The amp is biased to 25ma and he jumps the channels with a cable. It still has a superbass tonestack and a shared cathode - Dave Freedman

If anyone can make sense of this in terms of what do do in the fractals plexi models I would greatly appreciate it.
