1985 Yamaha Japan PB600R Precision/Jazz Bass MIJ (Black)
Released by Yamaha Japan in 1985, the PB600R was an upgrade on the original PB400R designs. They feature a single Jazz bass pickup in the neck position and a humbucker neck pickup (with a coil split activated via a push/pull tone knob). These had a reasonably short production run and weren't made in high numbers, rare old Japanese bass!
Good overall condition as pictured, plays and sounds great. See the pics for more.
