One of the most highly respected Guitar Amp Heads in the Marshall family, this 100-watt beauty is the next step for the acclaimed JCM800, one of the company's first amplifiers to feature a Master Volume control. This evolution of that landmark model retains the same simple yet effective approach, featuring one channel with no reverb to help please purists who like their sound natural but with plenty of roar. A tonally transparent Series FX Loop has been added to the 2203, granting instant and immediate transformation into higher, crunchier tones that are perfect for musicians inclined towards the sharp sting of metal.
