In a nutshell, the Marshall all-valve, 2-channel JVM210H 100-Watt tube head is a 2-channel version of 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 2 channels are completely independent of each other, and they boast 3 Modes, all 6 of which are footswitchable and feature their own unique gain structure. It makes the JVM 2-channel effectively 6 Marshalls in one. The JVM210H has studio-quality digital reverb with a level control for each channel. This is also footswitchable, as are the amp's 2 Master Volume controls and the Series/Parallel effects loop. Resonance and Presence are equipped with master controls.
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 4-way footswitch boasts 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 JVM210H all-valve amp head will give you whatever tone you need right when you need it.
