1 DCBirdMan 1 month ago About the Fender Bassbreaker 007 ... "but it uses the decidedly British EL84 to induce the famous mid-focused flavor from across the pond." .. ahh whatever EL84 was just the Euro designation for the 6BQ5... used in plenty of US amps, Gibsons and others... so this jive about how it's British means nothing. It's just an output tube ( good one) used in hi-fi amps, guitar amps. Seems like just marketing hype. EL 34 (6CA7) not seen in many us amps tho .. at least ones I know about.
