OVERVIEW
CHANNELS, MODES & MEMORY
Presenting the 4 channel, 100 Watt, all-
valve JVM4 amplifier (JVM410H head or
JVM410C 2x12" combo). Its 4 channels
feature 3 modes, giving you a total of 12
different modes to choose from - each
with its own unique gain structure. Even
though its front panel contains a total of 28
control knobs and 8 LED switches, JVM4 is
simple to understand and operate thanks
to its extremely logical front and rear panel
layouts.
The front panel contains dedicated sets of
controls for each of its 4 channels - CLEAN,
CRUNCH, OD1 & OD2 - plus MASTER and
REVERB sections. Each channel contains
the familiar controls, VOLUME, BASS,
MIDDLE, TREBLE and GAIN. The REVERB
section consists of 4 level controls, one for
each channel, while the MASTER section
is comprised of 2 footswitchable master
volumes: MASTER 1/MASTER 2, 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
Stompware® footswitch. To scroll through
the selected channel's 3 modes keep
pressing the said switch 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.
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 in orange mode.
In addition to channel and mode selection,
other features that are switchable via the
front panel and the footswitch are REVERB
(on/off) MASTER 1 & MASTER 2, and
SERIES/PARALLEL FX LOOP (on/off). All 3
of these functions are also remembered by
each mode.
To sum up, each of the JVM4's 12 modes
will remember its most recent REVERB,
FX LOOP and MASTER volume setting.
Additionally, mode setups can also be
saved and recalled to one of 128 locations
via MIDI.
STOMPWARE® 6-WAY FOOTSWITCH
The JVM410H and JVM410C are supplied
with a Stompware® 6-way programmable
footswitch, which can be connected to the
amp via any standard guitar cable.
Note: The supplied footswitch lead is
unscreened and not suitable for guitar.
The footswitch features 7 LEDS: CLEAN,
CRUNCH, OD1, OD2, MASTER, REVERB
and 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, REVERB and FX LOOP.
The supplied Stompware® footswitch
enables you to assign any of its 6 buttons
