So I've got a DRRI, and I'm looking to upgrade it quite a bit, I like it now, but I guess I just want 'more' out of it. What would you recommend? I plan on swapping out all the tubes and getting a new speaker (even perhaps chopping the thing up to make it a head +cab) I want to get a big, punchy, clean sound, something John Mayer-ish... I've been thinking about an OT upgrade... what else? Should I switch to a SS rectifier, can I swap to 6L6's instead of 6v6's to gain some headroom? Help...I'm clueless.
