About this amplifier.

The Marshall JCM900 4101 is a player’s favourite, an all-valve 100 watt Marshall with a 1 x 12” cab. The 2 x 12” cab is available, it’s the 4102. And this Marshall is available as a straight head – the 4100.

This amp is known for its great reliability and is a very versatile two-channel amplifier.

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 allows you to achieve a perfect sound for any lead tone from silky smooth to searing saturation. As well as having separate gain controls, each channel has its own master reverb section containing controls for Master Volume and Master Reverb.
