Picked up Bass #50 today. It's a Goya Ripper copy. Pretty authentic by the looks of it including selector switch and set neck. Nice mother of pearl inlay on the headstock. I've got a Goya precision copy and it's one of the nicest Precisions I have ever played. When I saw this one I jumped. I can't date it precisely but serial number starts with 02 so I assume 1982. It really dials in a wide variety of tones as well. The only problem is that it has been de-fretted But looks like nice job of it... I may think about getting it re-fretted but it may not be worth it. I know some of you may like fretless but in my opinion a lot of folks "ruined" their instruments in the 80s for a passing fade. (Don't flame me but that's the way I see it).
