So I hear that when it comes to aggression, the E34L is the way to go for power tubes. Anyone have any experience with them (tonally..not the "JJs are evil/unreliable" stuff)? Currently I got KT90s in the DTX and I don't think anything else will do anymore, but I recently tried some EL34s and it took me back to the good ol' days of when I first had the amp. I'd like some aggression in the power section, so if E34Ls can do it, I just might try.
