I need to know stuff. Played one of each, liked them, want to know more. Actually, come to think of it, I'm putting up a poll. I want quantitative data too. For a point of reference, the music I'd be playing would be a lot of U2/Police type 80s-influenced pop music to more current early/mid-90s stuff to more effect-heavy texture/atmosphere studio and live work backing singer songwriters. It's also possible I'll be getting a Beatles project going as well, for which one of these would be the no-brainer go-to amp if I bought it. If I can swing it for blues or gospel or soul/R&B/funk, fantastic, but I think my DR and my Bassman are better suited for those gigs. Specific questions: -What guitars sound best with each amp? -What are the shortcomings to be expected of either? -Obviously the Bad Cat is more flexible tonally and with the reverb, but it is worth the extra few hundred bucks? -Do either/both of these amps have issues with clean headroom at band volume? -What would you expect the Bad Cat to go for used? What would you offer for a clean Sampson-era Spitfire (the one I have my eye on - I don't know if I'd be willing to pay what the seller is asking)?
