Marshall - JVM410 - 100 Watt Head

100-Watt valve head / Valve complement: 5 x ECC83 (12AX7s) in preamp, 4 x EL34s in power amp / 4 independent, footswitchable channels

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.
