Made In: United KingdomIn 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..
