I have raised my bridge for slapping (with adjusters) to have a good string height with my Eurosonics. But doing this I now have an open string buzz, especially on the D string. The buzz is there whenever my slap his a little horizontal. When the movement of the string is perpendicular I have no problem with this. I am wondering if this is a nut problem or so other. Your ideas would be appreciated (and forget about refering me to Rockabillybass). Thanks.
