New here. I just bought a MIJ Telecaster Custom Reissue used. It looks mighty fine. Serial number on neck suggests it as '93-'94. However, I opened it up and discovered the HB appears to be alnico. I understood the MIJ HB were ceramic. How can I determine if I have a MIJ neck on a MIM(likely) or MIA(doubtful) body? Thanks for your insight.
