Kept tweaking my Rats today - and wouldn't you know it, my favorite settings are incredibly simple. Both of these give a nice cutting tone with a bit of clank (but NOT djent). Think a modern thrash tone like Overkill or Exodus but with a bit of hair. And it's not a night and day difference in brightness between my clean tone and the Rats.
Frost Giant Bass Mountain - Literally every knob at noon, except volume to taste. MOSFET clipping. Done. Criminally easy to dial in these settings, but it took me WAY longer than it should have to figure out... Not sure if I'm happy or annoyed to have found that these are the settings I like!
Blue Colander Tremond - Blend and Distortion noon, HPF max, Tone 1:30, volume to taste. Middle diodes (none!), and Master Volume as needed. Again, pretty easy, with no in-between settings or anything like that.
So now I've got my 5 tones down - and they all pretty much work for anything I play. Just depends on what tone I want at the moment. I've got clean, "tube dirt" (Pork Loin), "smooth distortion" (MBD-2), "rough distortion" (Bass Mountain or Tremond), and fuzz (Pharaoh Supreme).
On the topic of Rats, I never hear much about the Bass Mountain or Tremond. Wonder why that is? Seems like the few people who have tried them love them, but all I ever hear about is Broughton, Dunwich/Magic, and Fuzzrocious. Just idle rambling here.
Been a great couple of days, and I hope you're all having as good of a time as I am lately. Keep on doomin'!
