I've got a '74 Superlead that I've converted to '68 specs and it covers VH perfectly on it's own. I also have some Rangemaster clones that drive the heck out of it, but obviously lop off the low end. Other pedals include a BYOC tubescreamer which is great for pushing the Marshall into higher gain 80s tones. And I just recently got a Fulldrive II which adds more flexibility to the tubescreamer platform. What I'm looking for now is something that will push my Marshall into higher gain territory but have a tighter low end so I can do chuga chuga stuff ala Nuno Bettencourt (Pornografitti). I still want it to sound natural so I'm looking at the Brownie (or BSIAB), Crunch Box, and Plextortion. Any advice for me?
