Have only played it a short time, as I'm at work (my boss plays bass in the same band, but there are limits.) and can't completely crank it up. It sounds great. I wasn't looking for an exact retro sound, but you can tell the tweed 5E3 was the starting point. Lots of usable tones, (the main thing) so far, I love the way it combines both a Tweed and Marshall vibe. Wonderful, nearly fuzz free sustain at a reasonable volume, and a lot of tone control flexibility. I've enclosed a couple of photos one next to my SX STL Ash. The three cabinets are made by Lopo and the speakers are loaded with Eminence Texas Heats. One cabinet is open back and the other closed. I'll post a complete review when I have had it a while and played through it at a band rehearsal. At this point, I'm very excited about it.
