"The JMD:1 is the result of a unique collaboration with our friends at Softube, leading to a true digital pre-amp, integrated into a product that I am proud to see the Marshall name on."

Dr. Jim Marshall OBE

A New Era

With the Marshall JMD:1 amplifier, a new era in digital guitar amplification has begun. Marshall's analog excellence is combined with Softube's patented simulation technology to make rock 'n' roll's most comprehensive and sophisticated amplifier, while still staying true to the Marshall tone and heritage.

Inside the Amplifier

The JMD:1 is a guitar amplifier with both hardware and software jointly developed by Softube and Marshall. With a state-of-the-art digital pre-amp and a 50W or 100W valve power amp, the JMD:1 marks a new era in guitar amplification.

Natural Harmonic Technology

The 16 classic pre-amps in JMD:1 were digitized using Softube's groundbreaking Natural Harmonic Technology, which matches the behaviour of each pre-amp exactly, harmonic by harmonic, component by component, for any input signal and under any conditions.
