Caveats: I believe all of these circuits are 100% original, but I can't say for sure. Also, wiring is a very weak area for me. I won't try to interpret these myself, so those with knowledge please chime in!
The guitars here are a 1983 Nighthawk (August body/September neck), a mid-80s Skyhawk (haven't checked the dates, but the headstock decal and features put it between '85 and early '87), and a 1982 S-500 (haven't checked the dates, but the skunk stripe puts it early in the year).
