Sound — 10
It's very similar to a Fender Twin Reverb in appearance and layout but the MM I believe was designed to be a bit on the nasty side. Has a great power tube breakup for blues and classic rock. This amp is amazingly and painfully loud! The cleans are just that but it starts to sing when cranked higher. Very warm, punchy and precise. This amp really projects the sound across the room in a broad manner.
Overall Impression — 10
Amazing amp. I first played one back in the early '80s but haven't had a chance again since I found mine in 97. There getting scarce now and quickly becoming hot items for collectors. I have several amps but this one is far my favorite. It just seems to accent your playing and is not partial to any one guitar. It's very articulate and unforgiving to mistakes.
Reliability & Durability — 10
It's a Music Man! It's very heavy and solidly built. You could use this thing as a truck jack. Has 700 Plate volts so it does have a tendacy to eat tubes if you run it hard in high power for long periods over time. I've found that the JJ E34L's are great sounding and do take the high voltages very well.
