I've been wanting a 4 x el84 amp with reverb and tremolo for a long time so I've been excited to hear the AC30CC ever since I heard they were going to be built. I finally got to try out an AC30CC with blues last week. Sounded good but not as rich or 3D as I had hoped for. My real hope was to have it sound closer to a Matchless (ala John Jorgenson) It's just not there. A couple of days later, I went and demoed a Bad Cat Trem Cat. Just no comparison in the 2 amps IMHO. The Bad Cat is the richest most 3D amp I've ever played. Very much like a Matchless but more lower mids. I bought it! I played two gigs with it this weekend and loved it. It's not super loud but it fits so well within the mix. My band mates couldn't stop commenting on it. It's expensive but I don't know of any other amps besides Sampson designed amps that have this richness.
