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.
