So... I have searched the board for info on the pros and cons of the EL84 vs the 6V6 reverb driver on the Fender Vibro King. Can anyone chime in with further advice about this subject? I am considering a 1995 Vibro King that has the EL84 driver but am concerned about the fact that this circuit was eventually redesigned by Fender. Thoughts? I know its heavy and lopsided.
