About the Marshall JCM900 4501 amp:
The JCM900 4501 is the single speaker combo version of the JCM900 4500 head.
Marshall has specialised in the production of valve amplification since 1962. The unique tone and playing response of the valves has formed the cornerstone of the Marshall “Sound of Rock”. The JCM 900 models split into two distinct product ranges, the Master Volume SL-X and the Dual Reverb.
So although they share a common ancestry and have similar rear panel functions their applications are quite different.
