About The Marshall JCM900 4500 amp:

Marshall has specialised in the production of valve amplification since 1962. The unique tone and playing response of the valve has formed the cornerstone of the Marshall “Sound of Rock”, which we have modified over the years to cope with the changing demands of the evolving guitar player.

The JCM 900 models split into two distinct product ranges, the Master Volume SL-X and the Dual Reverb. Though they share a common ancestry and have similar rear panel functions their applications are quite different.
