I've had one for 4-5 years. It's my primary gigging amp when I'm using a larger setup. I don't know that it has a voice that's all its own, but it's very versatile. Channels 1 & 2 seem like flavors of Fender. 3 & 4 are Marshall-esque, and 5 & 6 get into more modern high gain. You can select low, medium, or high gain for each channel, and there's also a built in boost if you want to goose the front end. Dual effects loops, dual masters. All of it MIDI assignable/switchable too. Bright and voicing switches as well. Big iron, thick PCBs. Takes pedals really well. The head shells crack just by looking at them though.
Each pair of channels have their own preamp tubes, and not much shared topology between them, so not the usual circuit compromises you get with a channel switcher. It responds well to tube changes; you'll hear the difference in different tubes in the V1 positions. Lots of options for power tubes too, and easy biasing.
I think they were priced a little high for what they are, but some of that was probably covering licensing fees to Fortin. They are a lot of amp though, and I get some great tones out of mine. If you like to tweak things and having lots of tone shaping options, it's a great amp, but it takes a little time.
