Way back in 1990/1991 I bought a Peavey RJ IV/RJ4-it's a four string Randay Jackson signature model. They made some low/mid range models, but mine was all natural koa, with purpleheart stringers, neckthrough body, gold hardware, and within the control cavity in the back there is a 7-9 band preamp, where you can get varying tones-I think they are on/off postitions. Very light bass, and very smooth. It's been out of action for a while, and has some 'character', AKA visible use. Does anyone out there have one of these??? Anyone know anything more about them, besides that they are discontinued long ago?
