I use a Fender Strat with this amp. Single coil pickups. Sounds great with humbuckers but it is a little darker than the singles in my opinion. I play classic rock/blues/anything Vintage. This amp totally nails what I play. This amp is NOT a high gain amplifier. Try out a Mesa Dual Rec if thats what you're looking for. With the pre-amp all the way up, this amp growls, perfect for early Black Sabbath. Lower the pre-amp, crank that master volume, and you start to hear the AC/DC in it. AC/DC did in fact use JMP 2203's in the late 70's. I'm also not sure, but on the Let There Be Rock album, you can swear they're using JMP mv's. Plug this puppy into a cab with greenbacks, G12H30's, or even V30's and you will definitely hear "the" tone that is heard in the classic rock albums. If you plug into the clean input, and really crank teh volume (which is almost impossible to do with this amp) you also get a pretty nice tone.
Overall Impression — 8
I've been playing 5 years and I doubt I will ever need a new amp again. If it were lost, I would have definitely buy it again. I would get a non-master volume amp, but its really hard to get the tone I'm looking for without an attenuator or having modifications done (I'm not a big fan of mods). I wish that the guy who originally had this amp hadn't put an effects loop and then have it taken out. He also added a half power switch. On full power it is a stock amp, but mods like that just take value away from the amp. I also wish I had come upon and earlier model (1976 to be exact) instead of a 1980. But other than that, its perfect for me. The one thing I love about this amp is just the overall look and feel that it has. The head shell is awesome. The simplicity of it is awesome. Guitar -> Amp -> Cab. The classic rock setup. The power and standby switches are pretty cool too. Hope this has helped!
Reliability & Durability — 5
I only rated this a 5 because I haven't had this amp for too long. I haven't gigged with it yet. Obviously if you don't take caer of it, it wron't function properly. If you do buy one, DO NOT neglect it. They are not only awesome amps, but a piece of rock 'n' roll history. I believe that in 30 years or so, guitar players everywhere will be seeking for this tone. It can really only appreciate in value too with good care. The older things are, the more valuable they become.

My JMP was made in 1980 according to the serial number. I, as a guitar player, do not look for much variety. I doubt you would either if you're reading this review. For the classic sound, effects and features aren't needed. I gave this a 4 because it does have 2 inputs, high and low (would've given a 1 if it only had 1). High input is for more high gain and trebly stuff. Low input is more bassy and clean. Even with the pre-amp all the way, this input is still incredibly clean. Being 100 watts, this thing is LOUD. I would even venture to say that its the loudest amp Marshall has ever made. The master volume does allow for more versatility than a non-master volume amp.
