Marshall JVM410H

I've been dreaming about this amp for years and finally pulled the trigger. It's the Marshall tone I expected and much more.

The clean channel sounds great on green and orange, the crunch channel I like best on red with the gain low, both OD-channels sound great on orange. Both OD-channels can deliver more gain than expected, but it's not bad to have as a trick up the sleeve.

The included footswitch works as a charm: fast switching without noise and accepts a normal mono cable.

The dual master volumes make it possible to switch to a solo volume on every channel. This is great in a live setting!

The amp has 2 fx loops. The parallel one works just perfect with my tc flashback 2 delay (turn buffer in pedal on and the fx loop on amp to -4db). This is the first amp I encounter in which the loop actually sounds great, without loss of tone and without added noise. It actually made me buy another flashback 2, to enjoy more delay.

I should have bought this amp sooner. If you like the Marshall sound, you will like this amp.

I think I've played all Marshall amps out there and I've gained enough experience in 40 years of gigs and recording studios for writing this review. Let's talk about a 100 watts head..... This is stuff that has never been something manageable for sound volume and especially for home use until now.
Well, I turned it on right at home!!
As soon as I arrived I connected it to a Marshall 1960B cab and I started very, very carefully to turn the volume knob to hear the first 4 chords at volume 1.
THE REVELATION!!!!
Marshall finally learned!!
I had a DSL 50 watts head that at 2 volume was going to blast my ears ...
Instead the JVM at volume 1 sounds.... volume 1, without shaking the walls. And at volume 3 it really sounds at volume 3, without being unmanageable. It's not the classic Marshall that at 1 volume you don't hear and at 2 you are stuck on the wall.
Those days are long gone....
I stayed about an hour to try it both in the cleans and in the distorted maximums, I tried it in all combinations of the distortion stages: green, orange and red: each one has a sense, a sound, a change of sound colour that also encompasses the sounds of the most important Marshall heads made so far. With the cleans it sounds quietly jazz and the eq works great.
And I have come to the conclusion that it is absolutely possible to keep such a monster even at home and you can get perfectly valid sounds even at 2 volume.
Yes, you read it right: AT HOME!
Surely it handles much better than a 40 watts Fender Hot Rod Deluxe, there's just no comparison...
If you are looking for a definitive solution to have any kind of sound at home or in the studio, this is the amp for you.
You can't imagine how much fun you can have with all the sounds under your fingers. You can get your sounds with the channels selection and the booster with the Master Volume section (read the instructions). No more boosters or distortion pedals!!
Highly recommend the pairing with case 1960B (the straight one) for a complete sound. Have fun!!!

This amp can give you all that you need - so many different sounds you can get.

The knobs on the panel might look intimidating at first - but it's really easy to get used to.

THIS IS ONE LOUD AMP!

I only have one complaint - which has nothing to do with the sound. One of the protective plastic corners on the amp was missing a screw. I know it is nothing serious, but it makes me wonder what Marshall's quality control guys are doing.

Side note:
The grip handles on the cab i bought with the head starting cracking from the screw holes a few months after purchase (and I never used the amp away from home, wasnt carried around, etc)... Thomann were kind enough and very professional to send me a replacement set of handles. But the new ones also have cracks developing around the screw holes - and they have never been used. Defective - straight out of the box! MARSHALL, WHERE IS YOUR QUALITY CONTROL?! very cheap plastics being used at the expense of the customer!

This amp offers a million ways to be dialed in. Its amazing, what sounds and types of sounds you can get. On top of that, its exorbitantly loud but can sound great on low volumes, too.

The build-quality is great. There are no flaws, the amp looks perfect.

The endless amount of buttons has me wondering, what everything really does, what settings are safed and so on. I guess if i would use only one amp, this would not happen. In other words, its easy to learn.

The one thing bothering me a bit, is the transformers and the magnetic fields. No other of my 100W amps has this problem:
When used in a small room like (5x4 meters), you cant escape the magnetic fields and hear some humm (guess its like 50Hz) depending on how you hold the guitar relative to the amp.

All in all, its an amazing piece of equipment, i would buy it again everytime.
