The
Marshall JVM205H Guitar Amplifier Head delivers a comprehensive
range of tones built upon Marshall's peerless EL34
design.
This built-in England amplifier provides multiple all-valve
voicings that are accessible from the front-panel switches, MIDI or
via the revolutionary technology of the supplied footswitch. The
JVM205H also features a studio quality digital reverb, two effects
loops, silent recording capability, and two master volumes giving
you a vast array of footswitchable tones.

Outstanding
Tone
The JVM Series uses a carefully designed, 4xECC83 pre-amp stage to
generate the desired amount of gain, from the cleanest, yet
complex, clean imaginable to a vast palette of overdrives that
range from sophisticated and subtle to explosive and extreme.
Boasting a truly amazing array of instantly switchable sounds,
overflowing with harmonically rich tones and responsive fluidity,
every JVM mode exudes that unmistakable Marshall sound and expands
on it, effectively offering multiple Marshalls in one easy-to-use
package.
Ultimate Flexibility
Each totally independent JVM channel offers three footswitchable
modes which progressively add gain while offering a complimentary
tonal topology, making the JVM the perfect amplifier for any
situation. The JVM’s layout is simple and uncompromising with
dedicated Gain, 3-band EQ, Volume and Reverb for each channel. The
Master section, featuring Dual Master Volumes, Resonance and
Presence, finishes the concise layout, making each JVM a familiar
old friend that’s intuitive to use. Even with its
programmability, multiple channels and modes plus switchable
Reverb, FX Loop and Master Volume, each JVM is incredibly easy to
navigate and understand.
Seamless, Silent Switching
The onboard logic ensures swift silent-switching and remembers the
position of each front panel switch in every mode: Reverb (on/off),
FX Loop (on/off) and Master Volume (1 or 2). When returning to any
mode, switch settings will be exactly as you left them, even after
you’ve powered the amp down. This groundbreaking technology
combined with revolutionary footswitch technology, plus MIDI
switching capabilities, add even further to the JVM’s already
incredible flexibility.
Ultimate Control and Connectivity
Every JVM is supplied with a fully programmable footswitch. This
revolutionary, patent-pending technology allows single front panel
switching (SWITCH STORE) or entire set-ups (PRESET STORE –
Channel/Mode, Reverb, FX Loop, Master Volume) to be simply assigned
to any footswitch . . . or, even cooler, a mix ‘n’ match of both
modes. Housed in a rugged metal casing with blank panels on its
surface which allow the user to label the pedal exactly as they
want, the JVM pedal has no restrictive factory set-ups or
functionality barriers, plus it’s a breeze to program. It’s
multi-coloured LEDs reflect every front panel switch status so you
know exactly where you are, in the heat of a performance, without
the need to glance at the amplifier itself. The JVM’s MIDI In and
Thru connection means it can easily be integrated in a MIDI
switching set-up, allowing you to store and recall 128 amplifier
set-ups and enabling your MIDI effects board to easily control the
amp. With its built-in memory and switching options the
possibilities are endless!
Studio Quality Reverb
The onboard, studio quality Digital Reverb is routed in parallel
(ensuring no digital degradation of the direct signal) and mixed
with the direct signal by means of a valve. Specifically developed
for the JVM, the Reverb retains signal clarity in its tail and low
noise, analogue switching allows it to decay naturally when
switching the effect off or changing channels. In addition, when
the Reverb is switched off, it is totally removed from the
circuit.
Effective Control
Each JVM boasts two FX Loops that live on its rear panel. A
footswitchable Parallel/Series Loop with Level and Mix controls
plus a Series Loop with a Bypass switch. Combine the JVM with a
MIDI FX processor and a MIDI footswitch and the sky’s the
limit!
Silence is Golden
When on Standby, the JVM’s emulated XLR output is fully
operational, allowing you to record in total silence, a godsend for
those late night recording sessions.
The Tone of the Cone
Speakers aren’t just there to move air, they’re an integral part of
an amplifier’s tonal voice. To that end, all JVM heads have been
designed to be sonically complimented by every single one of
Marshall’s vast array of 4x12 and 2x12 cabinet offerings.
Building a Better Marshall
Every JVM is made at the Marshall factory in the heart of England.
Time-tested craftsmanship and construction are combined with the
latest advances in manufacturing technology, ensuring world-class
build quality and roadworthiness. Internally, the JVM circuitry and
layout has been kept as simple and logical as possible, ensuring
the integrity of the guitar tone and an incredibly low noise-floor
for such a high gain beast. Four, double-sided PCBs are used and
connections are kept to a minimum to ensure maximum reliability.
Only the best components are used to ensure very high quality and
all of the internal wiring and amplifier assembly is performed by
hand. Strict quality controls ensure every unit made is worthy of
the world-renowned and respected white script Marshall logo.
Meticulous valve selection adds further to the all-important tone
and reliability that are both synonymous with the Marshall
legend.
