I have attached the pickup to my instrument with the provided double-sided adhesive disc, but I get a very inconsistent sound. When I press the pickup on the top, the signal gets much hotter. What is the solution to this problem?

It seems that the pickup housing on its bottom surface is not making good contact with your instrument. Piezo pickups work on the principle of sensing mechanical vibrations from acoustic surfaces, which are turned into electrical signals. Piezo pickups need good contact with the acoustic surface to better capture these vibrations.

Your double-sided adhesive disc may not be making good contact. Please remove the one you're using and try the other one included with the package. Press firmly when attaching the pickup to the soundboard of your instrument with that disc.

Is the double-sided adhesive disk used for the AP-1 stick on piezo pickups removable, and will it possibly damage the finish of my instrument if removed?

Would your AP or UP series pickups work on a banjo?

Can the putty used to attach a stick-on pickup damage my instrument’s finish?
