A favorite among committed rock players; the JCM900 (Model 4100) is an all-tube 100-watt that returns for a triumphant reissue. The attribute that first won the JCM900 Model 4100 its legions of dedicated fans is its versatility. It is a two channel amp with the A channel voiced for sparkling clean tones on lower gain settings, building up to a rough and raunchy crunch when driven hard. The B channel is voiced to start where the A channel leaves off. Your lead channel can be anything from silky smooth singing lead tones to a searing and heavily saturated distortion. Discrete gain and master as well as discrete reverb settings round out the broad palette of timbres available on the JCM900 Model 4100..
