Sound — 3
This is where I'm going to have to differ with everyone. In theory, this is a perfect amp for anyone, it has an amazing versatility. However, the tone was definitely... Not for me. I have used this amp with a customised strat, a Gibson SG, a Fender Jaguar, an Ibanez RG... It simply doesn't work for me. The clean sounds sterile and lifeless, no matter which mode you put it on (the red clean is starting to get crunchy, yet it still sounds cold). The red crunch still isn't crunchy, even when the gain is maxed, it still sounds pretty clean; to me, this should've been the green crunch. The overdrive channels, though, were too gainy for me. Perfect for leads (though it still sounds a bit cold), but when I play rhythm riffs, I definitely want a crunchy distortion tone. All in all, I was looking for exactly the tone this amp doesn't have: a warm clean channel and a crunchy distortion. The clean, however, is cold, and the distortion is either not crunchy enough or too saturated.
Overall Impression — 5
To me, this amp is definitely overpriced. For the price of the jvm410h, you can actually get some great amps: if you want cleans, get a Fender Twin and you still have money to spare. If you want to play metal, you can get an ENGL. This amp really disappointed me, I really wanted to like it, and I had high expectations, but in the end, it really doesn't do it for me. If I had bought one, I would definitely sell it or bring it back.
Reliability & Durability — 8
I did use it without a backup all the times I've used it, and this amp has never let me down in terms of durability. However, it was not MY amp, so I can't really rate this.

First of all, I'd like to make something clear: I do not own this amp. However, I have used it as a main amp for a few gigs, and I thought I would review this amplifier, because none of the reviews I see her is reflecting what I thought of it. This amp is extremely versatile. It has clean, crunch and overdrive channels, and every channel has 3 modes, each with a color: green for the lightest, orange, red for the hardest (speaking of gain there). The footswitch included has 6 buttons: 4 channels (1 clean, 1 crunch, 2 overdrive presets), 1 volume boost and 1 effects loop on/off. I have used this amp at a total of 7 gigs, and it is definitely powerful enough for any gig. This is a 100w tube amp, it's definitely loud.
