So I got a new bass from my wife for Christmas. It's a Yamaha BB414. Plays and sounds great, but with the dry weather up here the frets stick out a bit from the edge of the fingerboard and are rough on my hand as I shift up and down the neck. Is this something I can do myself? Do I need a special file? We don't have anyone around here that does this kind of work so I'm on my own unless it's something I need to send my bass away to get done. I'd rather do it myself. Any help is appreciated.
