Anyone aware of the Dorada MIJ Gretsch line fron the late 60's early 70's? I just picked one up and can't find anything about them. Looks like its gonna be a Killer 12 though. Model 5993 I been playing Gretsch since an Astro Jet back in 67. I never seen one of these. Came in the shop yesterday and been hanging around someones closet for 30 years in no bag or case just plain filthy. But its all here and gonna work out fine. Anyone know anything about these?
