Let’s go back to the beginning. In 1962, in a small shop in Hanwell, Jim Marshall created and began selling the first Marshall amp, a JTM®45. From this the Marshall sound was born. This reissue meticulously replicates this original Marshall sound. Using the GZ34 valve rectifier, it works with the ECC83 and 5881 valves to generate the harmonic and unmistakable Marshall tone.
