Part 1: I seen a post from I can't remember who, but they stated that a mosfet power section (solid state) will behave like tubes. Does anyone know what he was talking about? Part 2: I found that the m-pulse sounds really wicked if you just crank the first stage of eq and then bring the gain up to before it distorts, or so. You can get a real nice clean tubey bottom, and when you start to climb the neck a smooth distortion starts to blend in. Is the first stage of eq on the m-pulse a tube eq or a solid state eq, that is does the eq run before or after the preamp tube? The mesa website says the m-pulse has a 4-stage vacume tube preamp, maybe this helps! Thanks to anyone who knows the answers to these trivial questions.
