Hi, I recently bought my dream bass SBMM RAY34CA only to find out that it needs some serious love in the fret ... area. I'm from EU and a new one would be just shy of 1K EUR so I bought it second-handed from UK ... so no returning it (I wouldn't really want to). The two (ex)luthiers in my town refused to do what I've asked them to do and tried to compesate the high frets with either a high setup, or telling me that I need to play with a lighter touch to not get fret buzz on the few frets. So I decided to level the frets (and cut the nut which is high) myself. I already have a fret rocker, so I have identified the high frets, a notched straight edge, and I'm thinking of buying a leveling beam and a crowning file (+all the smaller essentials). The thing is, I really don't want to have my first take on the job on my main bass, so I was thinking about buying a cheap guitar (they are much cheaper than basses) and trying it out on it. The question is, how different is leveling frets on a guitar, and on a bass? (and would you guys approve of this idea at all) Additionally to that, I am a little unsure as to what size leveling beam would be ideal for the job. Is a 16" (40 cm) beam ok or does it have to be 24" (60 cm) which spans the whole lenght of the neck. Thank you very much for your inputs.
