Here’s the real deal — a late-’70s Marshall JMP 2103 100W Combo, the same circuit as the legendary 2203 head, just packed into a 2x12 box. These don’t come around often, and when they do, they mean business.
Built in 1979 and made in England, this amp delivers that unmistakable classic-rock roar — bright, biting highs, thick mids and punchy low-end that’ll rattle the floorboards. Crank the master and it sings with that glorious EL34 growl we all know and love.
Loaded with original Celestion G12-65 speakers, it’s every bit as gutsy and dynamic as you’d hope. Cosmetically, it’s been around the block — worn tolex, a few scuffs and tears — but that only adds to its vintage charm. Fully functional and sounds absolutely killer.

Well used but fully functional. The tolex has plenty of wear, some tears and marks throughout, all consistent with age and use. Control panel shows patina, knobs and switches work as they should. The amp has been tested and sounds killer — huge tone, great dynamics, no unwanted noise. Proper vintage Marshall mojo.
