The 421D 421M and 421 Pro

This is the 421 Pro with the distinctive 12th fret design which is on some higher models

These three guitars were made from 1994 to 1999 all made in Taiwan. The D and the M appear in Japanese and Western catalogues of the time but I can find no official records of the 421 Pro but it certainly exists and there is some detail to be had in various places. Whilst the D and M are the same model except for the board they do come in different colours.
