Use whatever you want. In the end only one thing counts.... how does it sound? If you like the sound when it is dirty amped and also has one or more overdrive/distortion pedals.... go for it! It mihgt be unconventional, but that is what makes music evolve. If Jimi He drix and Eddie van Halen didn't do the unconventional thing we'd be playing completley different.
P.S.: my main overdrive is a Tube Screamer 808, though on Ceriatone, not a Randall.
Exactly.
Also, just recorded a clip that is a good example. If you want that nasty old school Swedish death metal grind...only one thing will give it to you...the Boss HM-2. Dirty, nasty but oh so glorious.

Yeah, I know, acquired taste...
Randall RM20 with the ultra XL (slightly dirty) btw...
