In a nutshell, the Marshall all-valve, 4-channel JVM410C 100-watt, 2x12" combo 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 three 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 JVM410C has built-in, 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 eight LED switches on their front panels, they're incredibly simple to understand because of the extremely logical layout. Each of the four 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 four reverb controls, and you're only left with four Master controls—two master volumes, plus Resonance and Presence.

Add to this an ingenious footswitch (U.K. 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 seven 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 JVM410C all-valve combo amp will give you whatever tone you need right when you need it.
