You know I'm surprised this topic hasn't come up more. I've always thought the JJ EL34's sound a little dark and with a little slower response time to playing. I love the Sino Chinese (Ruby's) EL34B's in most "Marshall" style amp I've tried and own.
Hey Dave, so what is your opinion on the Sino EL34's with the BE and your amps?
Would also like to hear others opinions on this besides the stock JJ's, if any else is running different EL34's.
