Channel Overview - Marshall JVM2 Serie Mode D'emploi

Channel Overview

The JVMʼ s front panel is divided into 2 main
sections: Channels and Master. Each of its
channels has 3 modes which are distinguished
by a different coloured light (green, orange or
red) appearing in the respective MODE switch;
the preamplifierʼ s gain structure is uniquely
reconfigured for each and every mode.
CLEAN/CRUNCH CHANNEL (8)
CLEAN/CRUNCH GREEN MODE: This is the
cleanest of the three modes and, in keeping with
traditional clean amps, it uses a simple and
straightforward circuit keeping the signal as pure
as possible. In this Mode the channelʼ s Volume
control is taken out of circuit as is the case in
vintage amplifiers of this nature. This is the only
JVM mode where this happens.
CLEAN/CRUNCH ORANGE MODE: This mode
shares the preamp topology of the classic
Marshall JTM45/1959 ʻ P lexiʼ models (i.e.: gain +
gain + tone) but with a bit more gain than is
found in the originals.
CLEAN/CRUNCH RED MODE: This mode is
reminiscent of the Marshall JCM800 2203
amplifier, a staple of hard rock. The gain
structure is gain + gain + gain + tone.
OVERDRIVE CHANNEL (9)
OVERDRIVE GREEN MODE: This is very
similar to the hot-rodded JCM800 sound found
in ʻ C runch Redʼ , allowing you to dial-in two
distinctly different yet similar crunch sounds if
you so wish - one in each channel.
OVERDRIVE ORANGE MODE: This adds
another gain stage to the ʻ O verdrive Greenʼ
circuit, resulting in a sound thatʼ s perfect for
singing leads and hard rock/heavy metal tones.
OVERDRIVE RED MODE: Adds more gain to
the ʻ O verdrive Orangeʼ for a high gain Marshall
sound.
