I've heard that Bjorns designs had fender amps in mind. With that said I have 2 musicman amps, one with 6l6s and one with el34s. Don't know if it's my imagination but the el34 amp seems to have this mid thing that keeps the BJFs from really shining. The other amp makes the pedals sound very hi fi.
Any experience? Or is it just my imagination, running away with me. (couldn't resist)
