From the first time I used this amp back in 2014 I knew immediately that it was something special and offered guitarists something that is pretty much unique - the ability to use one amp for all styles that they play. Versatility was king.

This JVM410HJS Joe Satriani amp made the alternate JVM410H sound like a poor sister - and I think that's still the case today. The 410H (as I'll call it) suffered in many ways to the Marshall amps that I was used to over the years. The internal build was different than this 'Satch' amp, there was no choke, the drive channels of that 410H amp squealed after about 9:00 on the drive knob and lots more. But sadly (in some ways) this JVM410HJS Satch amp that is reviewed here could easily be confused with that 'other' amp. Until you plug it in!

Fear not. Recently I have noticed for about the last three years or so many YouTube 'reviewers' 'discovering' the JVM410HJS Satch version amplifier. Where were these guys when the original was released? in kinder garden no doubt... but at least they are catching on to this Satriani monster amp these days. And no wonder.

Many guys will never have played a JVM410HJS or even seen one, let alone with all those features that this amp has against the regular 410H? Well I think that if you have never played this Satriani amp head then you would be in for a massive rude awakening. The JVM410HJS is most likely Marshall's secret weapon and absolutely the most versatile amp Marshall Amplification have ever made to date.

You will see in this video that I show a general overview, the chassis, the Power Transformer and Output Transformer, the main board and compare this to the 410H board, the choke, and more.

I also offer my opinion as an owner of over 20 tube amps and a number of Marshall amps. Don't be surprised to see that this Marshall amp is NOT built like some of the rubbish out there that is often called 'boutique' amplifiers, when in reality some of those amps are rather like the emperors new clothes. But this JVM410HJS really IS different.

Play any style you want with this amp - its got the lot. Prices are climbing too. So what better time to review this amp - a unique Marshall limited edition signature amplifier at it's 10th anniversary of its release back in 2014.

Now all we want is for this to come out as a 20w Studio version - come on Marshall, you'll sell tens of thousands!

I have spent considerable time creating this video entirely at my own expense:
