I bought a used 1987 Sabre from Guitar center online (I know) and the looks, the feel and size are great. I only have two days left to return it if I don't like it. I have two stingray basses 1979 and 1982 and the sound is great. With the Sabre bass unplugged and I pluck the D or the G string, it has a rattle buzz sound. The neck is straight and doesn't appear to be hitting any frets ? It has a string hold down tab for the D and G on the neck and I loosened it to see if it was affecting it and it's not. Any input of other things to check ? I like this bass and would like to keep it.
