We pride ourselves on our ability to invent, innovate and create new ways for guitarists to find their own sound, whether that be through all-valve, solid-state or hybrid technologies.
JMD:1 – Time Line and Amp History 2 5 7 9 ENGLISH 4 6 1 3 6 channel adjust both the speed and intensity of the effect to the guitarists taste. The re-issue, like all of Marshalls re-issued vintage amplifiers, was a painstaking recreation of the original unit and even features the same valve tremolo circuitry. Featured twice in the JMD:1, the 1974 provides part of the new sound created for the Crunch Vintage mode where it couples the tonal qualities of the 1974 with the EQ of a monster 1959.
