Marshall JVM410HJS Joe Satriani Signature Guitar Amplifier Head
Marshall is pleased to announce the Marshall JVM410HJS Joe Satriani Signature Guitar Amplifier Head. This collaboration between Marshall and one of the world’s most respected guitarists takes the well known front panel features of the JVM410H and overhauls the tone to a completely new level! The British made, all valve, JVM410HJS is a true labor of love that took several years of intense R&D with Joe who rigorously tested out prototypes on tour and in the studio.
Marshall JVM410H Joe Satriani Edition Amplifier Head Features
- Four noise gates help you dial in a defined tone on every channel
- Clean channel is the same design found in the Marshall LM6100
- Orange crunch channel is the same design found in the Marshall JCM800 (2203)
- Red crunch channel is similar to the Marshall AFD100 in AFD mode
- Overdrive channels sound more dynamic and open, thanks to a re-designed power supply
- 'Mid Shift' control on OD1 and OD2 shifts the midrange focus for extra tonal versatility
- MIDI input for configurable switching and control
- Footswitch included
At first glance, the Marshall JVM410JS head may look familiar. Taking a more detailed look though, will make you realize just how different this amp is from its stock counterpart. So, how is the JVM410JS different from the JVM410H?
Firstly, and probably most notable is the fact that the four Reverb pots from the original JVM410 have now been replaced with Noise Gates; four Noise Gates no less, one for each channel and each with their own threshold. Another visible change to the front panel is the addition of a ‘Mid Shift’ button that can be used for both OD1 and OD2 channels, shifting the mid character of the sound to that of Joe’s specification.
Tone wise, the JVM410JS Joe Satriani Signature head is very different; The Clean channel is based on the aforementioned 6100 when on the green mode, with the orange and red modes being hotter variations of that tone too. The Crunch channel takes the original JVM410 crunch and adds some of the popular Marshall ‘AFD’ circuit to it, and the OD channels are now both voiced identically, based on the JVM410 OD1 but with the gain scaled back slightly and a smoother transition between modes.
The rest of the Marshall JVM410JS plays out in familiar territory; the amp is still powered by EL34 valves, there are two Master volumes, the supplied footswitch enables you to switch between Channels, Modes, 2 Master Volumes, FX loop and now also the Noise Gates and Mid Shift. There’s also full MIDI implementation on the unit.
‘I had some real, practical experience with the JVM and I had some things I wanted to change about it
, ‘ Joe
states. ‘Specifically, to make an already great amp even bigger, bolder, more punchy and more dynamic. To me the JVM410H’s four channels were amazing but what was even more mind-blowing was that it had three switchable modes per channel. So it wasn’t merely a 4 channel amp, it was 4 by 3. It was fascinating just to sit there and play through it. I felt that the designer, Santiago Alvarez, had really made a huge step forward in amplifier design by being able to pack so much into a head while making it so elegantly designed and functional. This amp gets you in and out of all the different eras of rock music, no questions asked
‘After a really long and fruitful R&D period where I’ve been able to record, rehearse and play live with all the prototypes while Santiago and I fine tuned the amp…not just with Checkenfoot but on my solo stuff too
continues. ‘I’ve really put all the prototypes through their paces in the real world – well, in my real world anyway. To my mind, the original JVM410H has a sizeable chunk of Marshall History encapsulated within its 12 modes. I feel that Santiago and myself have capitalized and expanded upon that firm sonic foundation, and, as a result, the JVM410HJS contains a lot of classic Marshall tones as well as a few fresh ones that people will hopefully regard as new classics
