I'm in love!

If your looking around you may see this same review on another sight because I love the amp that much. I have always wanted a JCM 800 but didn't want to have to use an attenuator to play a 50 or 100 watt amp at the house. This amp is awesome and you'll love cranking the gain and ringing out cords. I find myself constantly ringing out G cords and just listening to its growling beauty. I want to address some comments made from others on the internet... Some argue it doesn't sound like the original 100 watt JCM 800. If you're splitting hairs there is a slight difference when playing in 5 watt mode vs 20 watt mode. 5 watt is excellent, 20 watt is the bomb! 20 watt seams to provide a little more clarity in the sound. Best sound I've ever heard! That said I still use 5 watt mode most of the time so it's still great to my ears. I'm only mentioning this slight difference because that's possibly the reason some say it's not like the 100 watt older brother. Side by side they may be right. But I would want the 100 watts of noise anyway. I bought the 2/12 cabinet that pairs with it. I play at my house and have yet to turn the master volume up to even half way because it's that loud. So playing with a band or in a club would be no sweat for this amp. This amp gives you the sounds of all the hard rock played in the 70's and 80's and 90's. Want to play zeppelin, Bad Company, AC/DC, Aerosmith, Motley, or Greenday or Zakk Wylde? This amp does them all to a T. I love it and very happy to have it in the collection. I would buy it again and again. Thank you Marshall for this amp.

Good tone, terrible effects loop

It's light, and sounds great. Not quite the beast that the 100W version is, but it's good enough for me. The main issue I have is that the effects loop is quite poorly engineered. They really should just have left it off, so people don't buy the amp expecting it to have a usable loop. When you engage the loop, the amp starts humming a little. Put a cable in the loop and it will start behaving like an antenna: the hum will increase or decrease depending on the orientation of the cable (needless to say, this doesn't happen with other amps). I've emailed Marshall and they confirmed that engaging the loop results in hum (on the bright side, with the loop disengaged, the amp is really quiet at idle, which is nice). I have a few high quality effects boxes, all of which sound bad in the loop. A lot of other people online have noted the poor effects loop, so buyer beware.

    This is an excellent Amp for home use where you don't need or want 100 Watts blasting in a small area. The sound is clean and with external effects, you can do anything with a clean sound source. I'm using it to back into playing my guitars and the clean precise sound lets me hear exactly what I'm doing wrong or right.

    I own a JCM 800 hundred watt head. I was given the impression that his amp would be the same but maybe not as much low end , but that is false it sounds nothing like a JCM 800. This is poor promotion and people should be aware of this. I played this app for about an hour and said to myself what junk. Then it cost me shipping to send back this poor design and falsely represented amp head. Very unhappy
