So I took what I learned in that poll of plucked bandsaw blades (the one here and the one at SMC) and I created a web site where I allow the user to take a few measurements of their blade and saw, and determine the optimum frequency of their plucked blade based upon their desired tension.
You can use a $13 chromatic tuner (like this one) to check your bandsaw's blade and see how close you are.
It should be pretty darn accurate. Probably more accurate than any clamp-on gauge.
If you're interested in taking a look, the page is here:
