NB: Please note that the supplied footcontroller lead is

unscreened and not suitable for guitar.

The 6-button footcontroller features 7 LEDS marked

CLEAN/MID-SHIFT, CRUNCH, OD1, OD2, MASTER, GATE

& FX. The LEDs for each of the 4 channels are 3-coloured

Green, Orange and Red, visually telling you which channel

and mode is selected alongside the status of Master, Noise

Gate and FX loop. The CLEAN LED also doubles as a visual

indicator for when the MID-SHIFT option on the OD1 and

OD2 channels is activated.

The footcontroller enables you to assign any of its 6

switches to instantly recall any front panel function (Switch

Store Mode) or complete channel setup (Preset Store

Mode) in any order and combination. For example, you

could program it so that:

SWITCH STORE MODE

Any footcontroller is assigned to act as any one of your

amp’s front panel switches: Channel/Mode; Gate on/off;

Master Volume 1/2 and FX Loop on/off.

If a switch is assigned to select a particular channel once

is has been activated, it can be used to scroll through the

three modes, just like its respective front panel switch.

PRESET STORE MODE

Each switch can be programmed to instantly call up a

combination of JVM button options to form a Preset. For

example, you could program it so that:

Footcontroller #1 = Crunch channel, green mode with

Master Volume ‘1’, Gate ‘on’ and FX loop ‘off’.

Footcontroller #2 = OD2 channel, red mode with Mid-Shift

“on”, Master Volume “2”, Noise Gate “off” and FX Loop

“on.”

All the settings are stored within your footcontroller; this

means it can be plugged into any JVM410HJS ampliﬁ er

and all your footcontroller settings can be instantly recalled.

Details on how to program your footcontroller can be found

later in this manual.

III. POWER AMP

The power amp stage of the 100 Watt JVM410HJS

is based on the same as the one found in the JCM800

2203 and 1959 Superlead ampliﬁ ers, responsible for the

legendary Marshall roar it has been adjusted to suit the

variety of tones found in the JVM. This section features

Presence and Resonance control to help shape the overall

tone of your JVM410HJS ampliﬁ er.

Your JVM is also equipped with a Silent Recording mode.

When the STANDBY switch is OFF the power ampliﬁ er

section is disabled but the rest of the ampliﬁ er remains fully

operational.

IV. NOISE GATE

Your new JVM410HJS is equipped with an ultra-fast,

studio-quality Noise Gate. Instead of abruptly cutting

the sound once the threshold is reached like some

noise reduction units, this Gate progressively attenuates

Presenting the 4 channel, 100 Watt, all-valve

JVM410HJS Joe Satriani Signature head. Its

4 channels boast 3 modes each, giving you

a total of 12 modes and no fewer than nine*

unique gain structures to choose from. Even

though its front panel contains a total of

28 control knobs and 9 LED switches, the

JVM410HJS is simple to understand and

operate thanks to its extremely logical front

and rear panel layouts.

I. CHANNELS, MODES & MEMORY

The front panel contains dedicated sets of controls for each

of its 4 channels - CLEAN, CRUNCH, OD1 & OD2 - plus

MASTER and GATE THRESHOLD sections. Each channel

contains the familiar controls, Volume, Bass, Middle, Treble

and Gain. The GATE THRESHOLD section consists of 4

Gate Threshold controls, one for each channel while the

MASTER section is comprised of 2 footcontrollerable Master

Volumes, plus master RESONANCE and PRESENCE

controls that work universally on all 4 channels.

Each of the 4 channels has 3 switchable modes. These are

selected by the MODE switch dedicated to each channel.

To select a channel press its respective MODE switch

(or step on the relevant button on the supplied 6-way

footcontroller). To scroll through the selected channel’s 3

modes keep pressing the said button and the colour of the

LED in the switch will change from green to orange to red

and then back to green. Doing this steps-up the gain level

each time (red being the highest and green the lowest for

each channel) and changes the channel’s tonal voicing to

suit.

When you leave and then reselect a channel, it will

automatically recall the last active mode as all 4 channels

remember the last mode they were in until a change is

made. For instance, if you select the Crunch channel’s

orange mode and then go to the Clean channel, when you

reselect the Crunch channel it will still be orange.

In addition to channel and Mode selection, other features

switchable via the front panel and the supplied 6-way

footcontroller are Noise Gate, Master Volume selection (1

or 2), and Series effects loop (on/off). All 3 of these options

are also remembered by each Mode.

To sum up, each of the JVM’s 12 Modes will remember

it’s most recent Noise Gate, FX loop and Master Volume

selection. Additionally mode setups can also be saved and

recalled to one of 128 locations via MIDI.

II. FOOTCONTROLLER (UK PATENT GB 2442765)

The JVM410HJS comes supplied with a 6-way

programmable footcontroller which can be connected to

the amp via any standard guitar cable.

OVERVIEW

the signal following its dynamics. The individual Gate

Threshold control for each of the amp’s four channels is

specially tailored for it and allows very slow decay times for

slowly moving guitar signals thus maintaining the natural

sustain, plus very fast decays for staccato rhythms and

short pauses.

One of the most instantly noticeable differences

between the JVM410H and the JVM410HJS is

that I’ve replaced the original Reverb section

with independent Noise Gates for each channel.

Reverb is a very personal thing and I’ve found

that for me a built-in reverb never works as

well in a professional setting as one you can

put in an FX loop. I also felt that the amp was

missing something that’s extremely important

for recording, especially as a lot of recording is

done live nowadays. That missing something? A

professional quality Noise Gate – because guitar

players need their gain up but they also need to be

quiet!

So, we swapped out the four Reverb controls

on the original JVM410H front panel for four

independent Noise Gates which are just fantastic.

Boy do they make my life easy. I don’t have to do

a bunch of pedal-board tap dancing turning things

off and then back on again, in-between phrases.

It’s also a great way of keeping my stage noise

down to a minimum & I also think it’s less

distracting for the audience not to be overwhelmed

with hiss and noise in those supposed “holes of

silence!” Plus, of course, if you want you can

switch them off and go old school, which is great

and I’ll do that on occasions. Sometimes though,

I really just want to be able to blast with a lot

of gain, but also need it to be completely quiet

when I’m not playing, and for that the four gates

are just fantastic.

*Note: as you’ll learn from Joe, channels 3 and 4 are identical – hence nine

different gain structures, as opposed to 12.

THE BASICS

WARNING: Before going any further, make sure your

ampliﬁ er is compatible with your electrical supply. If

you have any doubt, please get help from a qualiﬁ ed

technician - your Marshall dealer can help you in this

respect.

The correct value of mains fuse is speciﬁ ed on the rear

panel of the ampliﬁ er. NEVER attempt to bypass the

fuse or ﬁ t one of the incorrect value.

Note: Please ensure the ampliﬁ er is switched off and

unplugged from the mains electricity supply whenever

it is moved!

Getting Started & Powering Up

1. Make sure that the speakers/cabinet(s) are connected

to the correct impedance LOUDSPEAKER jack(s)

on the rear panel (14). See page 10 for speciﬁ cs

regarding impedance matching. If you’re using an

extension cabinet make sure it’s powerful enough

to handle a 100 Watt amp and also that you’re

using a proper speaker cable. Never use a screened

(shielded) guitar cable for this purpose

WARNING!

1. Failure to do any of the above will damage your

ampliﬁ er.

2. NEVER use your amp without a (speaker) load

attached when the Standby Switch is ON.

Marshall recommends you always leave a (speaker)

load attached to the unit.

2. Ensure that both MASTER VOLUMES on the front

panel (6) are set to zero.

3. Connect the footcontroller cable to the footcontroller

and then connect to the footcontroller socket on the

rear panel of ampliﬁ er.

4. Connect the supplied mains (power) lead into the

MAINS INPUT on the rear panel ﬁ rst and then into

an electrical outlet.

5. Plug your guitar into the INPUT jack socket on the

front panel.

6. Turn the front panel POWER switch on. This will

glow red then wait for a couple of minutes.

7. After waiting a couple of minutes, engage the

STANDBY switch. Leaving the amp on ‘Standby’ for

a period allows the valves to come up to their correct

operating temperature. In order to prolong valve life,

the STANDBY switch should also be used to mute

the ampliﬁ er during breaks in a performance.
