This is a Marshall JMP-1 rack mount tube Pre-amp. This thing is unbelievable, and has every Marshall amp programmed in it, as well you can adjust every channel to your liking or set your own channels. Manual, Stereo Effects loop, stereo outs, speaker emulator, midi ins/outs. Pickup on the Westside of Jax, or I can meet in Riverside, Murray Hill, or OP.
I’m selling my whole rig, so I have these rack mount units available:
Marshall Monobloc Tube Power Amp
Furman Power Conditioner
3 space rack drawer
Viking Shock Mount Rack (13 space)
JCM 900 Lead 1960 Bottom Cabinet
