I am going to be selling my Stingray and would love to know its age (I got it second-hand several years ago) It is an Ernie Ball made, 4-string with only three knobs (volume, bass & treble). It has a serial number on the bridge #35469. I have replaced this with a 4-string Warwick FNA Jazzman that I got second-hand on e-bay. This has a serial number of #G (or 6) - 086194 -01. Can anyone help me in establishing which years these guitars were made please?
