So after getting a good setup on my SX bass recently and upgrading the parts to what I want, I decided that I really like this bass! The feel of the neck on it is better than any other bass I've played recently, but as it's fairly inexpensive, the fretwork isn't the greatest. There's no major problems with it and Grasshopper at Bass Central set it up for me after I got it and he said the neck straightened out very nicely. So since there's no major construction flaws, just some very minor (not even really audible through an amp) fret buzz, I'm thinking I want to try my hand at leveling the frets some to work that buzz out. The neck is set where it needs to be now after that setup and the relief is perfect at what it should be. So how would I go about working on the frets? I don't have any special fret files, so would some really fine sandpaper work on them? Keep in mind the replacement necks on an SX are only $40 so I'm not too worried about messing it up, but I will be very careful. Do I just leave the bass set up the way it is and slowly take some off the fret that it's buzzing on (usually the one right past the one being played on) until it stops? Obviously if it doesn't work out easily I'm not going to take them down very far or anything. Any tips for this project?
