The Marshall 2245 JTM45 30-watt head is an authentic reissue of Marshall's very first amp, the JTM45. Celebrated by guitar enthusiasts for its groundbreaking sound, the original JTM45 has become a true classic, and the 2245 JTM45 authentically recreates its inimitable tone. This meticulously designed reissue is incredibly accurate, and the key is the painstakingly reproduced GZ34 rectification. The rectifier interacts with the other valves in the amp to create subtle harmonics that shift and smoulder under notes, producing the one-of-a-kind, much-emulated Marshall sound. Loud and dynamic, the two-channel 30-watt Marshall 2245 JTM45 amplifier recreates a true vintage '60s tone.
