Hello guys, just a new doubt, I´m at the point of changing my whole stack, from Peavey XXX to 5150/Mesa or Bogner, but one think I will miss is......clean sound!!!! I dig the clean sound of MH and sometimes I ask to myself, is it a 5150 really? So I supose they will use a different tubes from standar, if I am wrong correct me, but standar tubes in 5150 are Electro Voice 12ax7 and Ruby 6L6GC, do you have any idea of which brand they actually use??
