The Marshall JCM900 4100 Guitar Tube Amplifier Head is an all-valve 100 Watt Marshall Head, known for its great tone and reliability.
The Marshall JCM 900 4100 Amplifier Head also features two channels, A and B. Channel A has been voiced for a sparkling clean on lower gain settings, building up to a raunchy crunch when driven hard. Channel B takes off from where Channel A finishes with acute use of the gain and EQ controls. This achieves a perfect sound for any lead tone from silky smooth to searing saturation.
Each Channel also has its own master section containing controls for Master Volume and Master Reverb. A Series Effects Loop with level controls lets you connect and match either floor pedals or rack effects.
