Forgive the start of yet another thread on this topic but... I've got a DRRI and although I'm happy with it's tone, I'm finding I need to tweak down the treble knob on the reverb channel to dial out some of the harsh brightness esp when using OD pedals. It's completely stock and I've allowed ample time to allow the amp and speaker to break in. I may eventually swap out the speaker and definately replace the tubes. For right now I'd like to see about saving my $$ for another guitar with a Bigsby. Sorry, I digress... I've heard that clipping the bright cap is one of the easier mods to do to really help this amp's overall tone. How difficult is this to do and who on here has done this? Did you do it yourself or have a tech do it? How do I find the bright cap? Finally, I'm reluctant to do this because of the dangers associated with the voltages stored up inside the caps. What good is it to have great tone if you're not around to use it?
