Re: Need to Identify older RG550 year
The RG550 never had scalloped fretts so that info wont help.
My DY had the matching colored headstock and it was a 1990 model, possibly what yours is.
But someone will have a more informed answer then me. Unfortunatly without the serial number, its gona be hard to accuratly pinpoint the exact date...
after re reading your description, I find it weird that its the original edge with a screw in type whammy bar.
Why not post up pics, that will help alot more...
