As part of their 50th Anniversary celebration, Marshall announced the release of the JMP-1H head. A 1 Watt, all-tube amp that pays homage to the era of the 1970’s Marshall tone and ascetics. One of two that are the second in a series of five Limited Edition pairings – each paying homage to one of the five decades that Marshall has been in business.

The Volume control sets the overall output volume of the amp, as well as its gain, for musical distortion as the internal tube stages are gradually overdriven more and more. The Treble and Bass controls give you further tonal control so you can get the JMP sound that is perfect for you.
