Years ago during our lessons, Paul O’Dette recommended that I attach my tastini with glue as he did, but I resisted because when I would change the tastini for whatever reason (new temperament, new string, etc.), I would make a mess of it. Recently, however, Grant Tomlinson showed me how to easily remove a glued on fret or tastino with a very thin palette knife such as the one pictured on your left. This led me to adapt Paul’s approach, and now I am much happier with the glued on tastini than the taped on tastini I recommended in the book. They are more secure and look better without the little icky feeling you get when your fingers touch the tape or that faint crinkling sound you hear if the tape isn’t completely flush.
Here’s how it looks on my theorbo. Much nicer, don’t you think?
