Value is hard to assess without seeing the guitar, but I'd say the range for this is US$1,500 – 2,500. These older Artists start at around $1,250 in decent (player) shape, but yours has the active electronics and those are a bit rarer.
Doesn't look like yours has the original pickups, which is a shame and hurts the value a bit among collectors. The rest of the hardware looks original, although I can't tell if the knobs are Sure Grips. Are any of the other tuners missing covers?
A common issue with these is badly decayed binding. How does yours look?
