Sound — 8
Brown tone, Satch and Vai leads, thrash metal. You have it, except for that nu metal sound. I put a Boss GE-7 through the loop, good enough to satisfy the metal heads out there. Also, that clean GREEN channel tone is amazing, I fell in love with it. So crisp and clear. I mainly use a Fender 50th Anniversary American Strat for blues and clean tone and a Prestige Ibanez RG2550E for those soaring leads and chug, chug sound. A few issues. It's a little noisy using the RED channels (high gain). I've eliminated most of the noise by using good cables, yet a noise gate is the ultimate solution. It's a high gain amp. What do you expect from it.
Overall Impression — 9
I've been playing for 15 years and I just wanted to upgrade. I was reading the comments so I decided to add this. I own a MG100DFX. The amp is great for what it is, but it isn't a tube amp. Marshall or not. Harmonics, tapping, sustains, etc. are easier to achieve on great amps. You will sound and play better on great tube amps. I looked at Mesa's Dual Rects, Peavey 6505 and Soldano. My friend owns the Mesa Dual Rectifirer, so I am fully aware of what it can do. That thing is a beast, heavy and dark. Like what I said. Every amp is different. We all have different tastes. I chose the JVM for it's versatility and price. I don't have the money to spend on 4 amps to dial in all the tones out there. The JVM gave me the clean tone that I've been looking for and gain to play my leads. I hope my review helps.
Reliability & Durability — 9
I've had it almost 2 months now. No major issues so far. I did find 2 pots that were scratchy. I used some electronic cleaner to fix the problem. As far as the Marshall Brand, no problems throughout the years. Tubes are tubes. They will have to replaced down the road.

Here we go. It's made in 07. I've had this amp for 2 months now. I actually own the head (JVM-410H) paired up to a 1960A (4x12). 4 main channels, with 3 gain settings on each, plus 2 volume controls on each channel. Add them up, 24 channels. The foot pedal is programmable to control each volume, reverb, effects through the loop for each of the main 4 channels. You can also hook up a midi and program the foot pedal to control your rack mount effects through the loop. Great feature, even thought I don't own rack effects. For the versatility and price, you can't beat it.
