In a nutshell, the Marshall all-valve, 4-channel JVM410H 100-Watt tube head
is the most versatile Marshall amplifier ever made. It also boasts more gain
than any other Marshall to date--and that's really saying something!
Each
of its 4 channels—Clean, Crunch, OD1 & OD2—are not only completely
independent of each other, they all boast 3 Modes, all 12 of which are
footswitchable and feature their own unique gain structure. It makes the JVM
4-channel effectively 12 Marshalls in one!
The JVM410H has studio-quality
digital reverb with a level control for each channel. This is also
footswitchable, as are the amp's two Master Volume controls and the
Series/Parallel effects loop. Resonance and Presence are equipped with master
controls.
Even though the head and combo both house 28 controls and 8 LED
switches on their front panels, they're incredibly simple to understand because
of the extremely logical layout. Each of the 4 channels has the usual suspects
when it comes to controls — Volume, Bass, Middle, Treble & Gain--accounting
for 20 of the 28 controls right away. Take away the 4 reverb controls and you're
only left with 4 Master controls--2 Master Volumes plus Resonance &
Presence.
Add to this an ingenious footswitch (UK patent pending) and the
fact all the amp's switching (channel/modes, Reverb, Master Volume selection, FX
loop) can be done via MIDI and you're looking at an incredibly flexible amp! The
6-way footswitch boasts 7 LEDs and memory, plus it connects to the amp via a
regular guitar cable.
From the cleanest clean to the filthiest distortion
ever found in a Marshall and all points in-between, the JVM410H all-valve amp
head will give you whatever tone you need right when you need it.
