Thank you so much for your response. Yes, I’ve done all the homework I can on the topic before bothering anyone. (Like you I’m sure, I get really annoyed by folks who just want others to do the work. Plus, I really enjoy learning.)
The thing that bothers me the most is that…
A. The 9,000 number is SO high.
B. The first numbers could have (unlikely) been stamped upside down and be 6096 until the last stamp came in.
C. Only the top half of the ES-125 didn’t get stamped, so whoever was in n charge of stamping might have skipped his coffee that morning.
Anyway, I bought the guitar and I’ll check the pots when it arrives. but it’ll still be interesting and good information about how high the FONs go.
