The Marshall Amplification JCM900 was the next evolutionary step on from the JCM800. The 4100 is a precise reissue of the JCM900, first launched in the early 1990s.
This high gain, dual reverb, all-valve 100 Watt head is still a players’ favourite. Known for its tone and workhorse roadworthiness, the JCM900 4100 has many fans due to its feature set and versatility.
Channel A is voiced to be sparklingly clean on lower gain settings, building to a raunchy crunch when driven harder. Channel B takes the gain higher producing tones from silky smooth distortion to searing, saturated scream.
The JCM900 4100 is equipped with a series FX loop with its own level control for use with rack FX or stomp boxes.
