I want to hear the DC-3 in action based on your experience. I believe you said on the KF that you never quite liked the peavey product, which is always something I've ended up owning. But I like some things I've heard in the Mesa lineup and glad you ended up with a satisfactory rig.
Not all Peaveys ... just the guitar amps I've played through. My large club bass amp, for example, is a Peavey Max 450 and I love it. The rhythm player (remember rhythm players? ... lol) in my last band had a Classic 30, and I always thought the distortion was really harsh, but to be fair, it wasn't mine, so I didn't have time to play with it. Patience is definitely a virtue, but sometimes it doesn't come easy to a musician, as we've all found out at one time or another.
I think it comes out to what you're comfortable with, what sounds good to you, and where your tone comes from. It can come from what pups, pedals, amps, chord voicings, damping, what have you. Some people like one signature tone from the amp, and control the nuances by switching pups or even guitars. As time has gone along (okay, as I got older!), I liked my rhythm cleaner while I'm singing, but I still like the idea of kicking the EQ to get the tone boost with the notch. I love the vocal-like sustain of the EL84s in my DC-3, or the 6L6s in the bigger Single Recto. The "Mesa Sound" is my signature lead tone. But not everyone agrees on even what the "Mesa Sound" IS ... I've heard people describe it before, and it didn't sound like my interpretation. Who's right? I suggest that we all are.
