Marshall Super Leads were the rock sound of the ‘70s used by legends such as AC/DC and Led Zeppelin. The all-valve 1 Watt JMP-1C combo has the look and, more importantly, the tone that defined an era.

Driven by true class A power stage topology, the JMP-1C is a classic rock amp. Its incredible tone is partly produced by an extra ECC83 valve gain stage in the preamp. It is this that gave the Super Leads their distinct tonal character that is now embodied in the JMP-1C.
