Okay, I have a question regarding tubes, more specifically tubes in the power amp. How much of an affect on the tone do power amp tubes play? In other words if I had a Mesa Studio Preamp (or any tube preamp), would there be a difference in sound between a tube power amp or a solid state poweramp driving the preamp? On the same note, amps such as the Fender Champ 25 SE, I believe use 2 6L6's and 1 12ax7. How much of an affect does 1 preamp tube affect an amp as well? Anyways, more questions to come later I'm sure, but any help is appreciated. Thanks!
