This is a good solution for some bows.
unfortunately there are quite a few limb designs out there that do not have enough tension on the string at brace (Pre Load) to stop the limbs clean.
So instead of transferring the stored energy in the limbs to the arrow shaft, a lot of that energy stays in the limb, and the limbs oscillate. this causes unwanted vibration, and often times noise, or that hum you are referring to.
Some of these bows just adding additional brace height can help out a lot. some of them it wont help at all. The tough ones are the lighter weight under 50# recurves that have limb bulge issues. This results when the pre-load is fine, and the limb tips are stopping dead, but the middle portion of the limb continues forward in a bulge.
Limb savers are excellent for limb bulge issues. they should be located right above and below the fade area of the wedges to do the most good and not rob your performance.
Hope this explanation helps.... Kirk
