The 86 in the SN says it was born in 1986. The lack of a letter after the 86 denotes Series. The presense of CVQ knobs instead of Q switches, and the master volume, means Series II rather than Series I. That's the Balanced Omega body, which is not very common. Beautiful bass! The position of the neck pick-up logo, however, indicated that it is mounted 180? off.
