Marshall JVM410H HeadThe Marshall JVM410H head is possibly Marshalls most versatile amplifier to date. As you would expect, this is a 100% pure valve driven box of lovelyness with many hidden extras inside. Needless to say youll get all the great tones that can be found on the TSL & DSL ranges, but the JVM410H takes it one step further. (to eleven if you will) Firstly you get an extra channel to play with, making 4 in total, and with 3 modes per channel - youll be sculpting tones youd never thought it possible to sculpt before! In addtion to this the JVM410H features independent volume/gain & reverb controls for each channel and dual programable master volumes, which is perfect if youve got a complicated live/studio set up. With fewer channeled amps, what sounds right on 1 channel may sound totally out of place on another, and these independant controls allow you to be more exacting with your sounds. Add to this a silent recording mode and 128 programmable Midi system, and its easy to see why the JVM410H is a popular choice for professionals and amatures alike. Highly versatile, and sounds great!
