Re: JMP-1 through 2204
Billy Gibbon's tone is constructed that way. His rig always changes, but it's usually got a JMP-1 going. I think they're better mated to a Marshall, Mesa, VHT, or Peavey
stereo power amp, though, to take advantage of the wider stereo sound.
If you tweak that preamp just right, it'll sound best through a Marshall's FX return jack,
but possibly good straight into the front, if it doesn't have an FX loop.
