it's truly nuts that the jx3p has gone up in price, it's not a very interesting instrument by any stretch
before vintage prices went really crazy most people scoffed at it
Maybe they did, but when you get stuck in to programming it via the PG200, you realise there is a lot to this synth, not least because of it's two oscillator voicing with cross-modulation pathways. Lately, the midi retrofit/control options (by organix and kiwitechnics) really open it up and increase it's sound potential.
Mine sits above my JP8 and I'm often impressed by how well the sound stands up next to the "bigger" synth...
oops, now I'm probably sounding like that stuck record.... ;-)
