This is a British made 4 channel tone monster. I always can find something wrong with every amp I own or play. Not this one. It has everything you could want for feature wise. Two FX loops, MIDI control, full EQ for each channel, line out, two master volumes and all the gain you will ever need. One difference between the JS and standard 410H is the reverb pots have been changed to noise gates. The gates work flawlessly. Also the clean channel has been changed to the 6100 clean. The original 410 had a GREAT clean and it probably should have been left alone but I think the new clean cuts better and that is why Joe wanted it. The clean channel takes pedals, especially distortion, and makes 'em shine!

This amp does everything. It has any tone you need. Jazz & country with the clean channel. The crunch channel is phenomenal, much better than the stock JVM. On the crunch you get the JMP tone on green, the JCM800 on orange & the AFD circut on red. It can do rock, hard rock & metal. The clean & crunch alone make a great amp all on their own. The od channels have more gain than you will ever need. The gain is slightly scaled back from the stock version. I know that may bother some but I felt the od channels on the stock JVM were too much. The JVM410H has totally unusable gain with the knobs set past 9 o'clock. With this amp the ENTIRE gain range is usable. No doubt the noise gates help, but the gain itself is a bit smoother as well. A note to you guys who like the to scoop out mids; get an EQ for the loop. This amp is Marshall in-your-face midrange personified. EMGs and other high output pickups tend to muddy up a bit on the od red modes. I just use them on the od orange and they sound great! No big deal, I'll just use the od red with my Jackson KV2 with Duncan pups!

Had no problems yet so... I can't say. I have however seen the inside of these things and they look to be well built. If I toured or played extensively I would get a head case for it. There is a lot of plastic input jacks that would make me nervous. The original stock JVM410H had all of it's resistors, caps etc. And front and back ins & outs on one motherboard. It also had loose potentiometers on the front. The JVM410HJS has a main board inside with the ins & outs on their own boards for easier servicing if it should be required. Plus the pots in front are nice and secure. Make no mistake - the JS is a completely different amp than the stock JVM410.

If you like an amp with a lot of versatility you just found it. I love this amp! You can't do better for under $3000. This was chosen over: Engl Powerball II, Engl Fireball, Engl Savage 120, Diezel D-Moll (this was my second choice, but it's $600 more and has only 3 channels), Bugera Tri-Rec, Carvin V3, Carvin Legacy, Fryette SigX, every Mesa Boogie and Marshall model available. Yes there are better amps out there, but this stands out in my eyes because of it's versatility and bang for the buck. All of this plus a ton of classic Marshall tones in one amp.
