I got a MV50 Boutique 6 months ago and am very happy. Pretty versatile, not a one trick pony amp at all. I coupled it with a Vox Stomplab and there's noe not much it can't do. I also got a Rock MV50 a month ago to compare, who knows eh ? Well that one has a narrower tonal palette, pretty much Rock and then more Rock. Once you're past 20% on the gain knob, you can say goodbye to cleans. It's now up for sale. I started by playing the Boutique through my 2X12" home made cab with Jet City Eminence, which are pretty neutral in tone. They don't color the native sound. It was VERY loud and with good definition. I then played it with my 2X10" cab (Vox Celestion VX10), much better with tighter lows and mids. I then built an experimental 2X10" cab with again the same VX10 speakers. I built it with the speakers installed on two different baffles at 90°. Very interesting how different they sound from the classic 2X10" cab. If I play facing one speaker only, the other seem to have a milisecond natural delay in reaching my ears. I like it.
