The Yamaha RGX 300 range



No 300s appear in the Archives, but there are several models. There is a 312 model and 5 or 6 321 models all made in Taiwan or Indonesia. It appears in Western catalogues but not in any Japanese ones that I have access to maybe just an export model.

These three guitars were made from 1991 to 1994 really only 2 models the FP is just a P with a transparent pickguard which allows you to customise the look of the guitar by putting artwork under the pickguard. For more detail see RGX home page

The more observant of you will notice that the only real difference between the 2 models is a pickguard, the pickups may be different but I doubt it.

Some catalogue scans of the 321 and the 321P

As well as the pickguard you can see that the P has different controls but I haven't been able to ascertain if this is true for all of them or if it's a body colour thing


The headstock which is the same on all three models with the exception of the model name

The 320FZ

RGX321D and 321DM

These guitars are not featured in any catalogues I have access to nor in the archives and information on the web is sparse. A while back a man called Rod Francis published information on every Yamaha guitar he could find. I was helping him with a new version in 2017 but he didn't complete it. The information I have on these guitars is from him thanks Rod. There are a few pictures of these about so they certainly exist.
This is the information Rod had in the 2017 draft
