Hi all, On my project bass (SX P/J) I set up the neck relief, action height and intonation well. I've done this countless times with no problems on my other and friends basses. However, only one damn fret is buzzing when played, it's 14th fret on the D string. Every other note is spot on, but when I hit that one, I get a god awful buzz. I can raise the action up to 3/32 with the buzz eliminated, but I much prefer my action really low, such as 1.5/32 on my Yamaha. As I've never touched a fret file, would it be best to send the beast to have the fets levelled? Also, is there a tutorial on nut carving? I would really love to learn how to do this as I prefer brass nuts and am sick of paying someone else to do it.
