im also having a buzzing problem with a fretless bass. i refinished the bass and i have a buzz on the g string about where the 9th fret would be the rest of the way up the the end of the neck. i made my own nut and radius sander to sand the neck a bit to remove the groves left by round wound strings the previous owner used on it and am tryin to set it up now and everything seems good except that problem. also could use some set up tips on a fretless, i cant seem to find anything on it, like truss rod adjustments and aprox string heights. any help would be great.
i checked for flat spots with the straightest thing i could find and havnet noticed really anything, but the ruler is prob not ery straight.
thanks
