About the Marshall JMP 2203 amp:

The Marshall JMP 2203 is one of those amplifiers that was almost exclusively used throughout the ’80s. It was a great tone and had a fast pick attack that was used by almost every guitars throughout the decade. It’s a one channel amp, with two inputs with different sensitivity.

So the “Low” input will give you a clean sound even on full preamp gain. The  “High” input will be much louder and dirtier.


There are six controls on the front of the amp besides the Power and Stand By switches.  Presence, Bass, Middle, Treble, Preamp Volume, and Master Volume. Presence controls the number of high frequencies and should be adjusted to match the guitar and the room you are playing in.

The EQ section is simple, but you should take some time to understand it. Preamp Volume controls the preamp gain, and when plugged in the High input can make your sound clean or totally dirty.
