I’m doing a bit of amateur repair this weekend to get my old Kay to make it through a show next month. I’m going to sand down some buzzing areas on my fingerboard in first and fourth positions and move the soundpost around as I’m not getting a decent sound right now with the bass. This will be the last time I’ll be doing such a repair on this fingerboard as the bass is going to the luthier sometime this summer for a new setup, neck reset with a nice ebony fingerboard, nut, Aubert bridge and a new tailpiece and endpin. Before when I’ve completed the sanding, I’ve simply just put the strings back on and that was that; but I’ve read some of the forum threads here on Talkbass that discuss how rubbing the completed fingerboard with either boiled linseed oil or tung oil will effectively seal the wood after such a repair. Which would be better to use? It seems like there’s about a 50/50 split in the responses on those threads as to which works best. Thanks.
