If you want to install our pickups and you’re working with a pinless bridge (as used in ukuleles, Breedlove or Takamine type guitars), you can search on YouTube for “under bridge pickup instal on pinless bridge” and one of the top results show how you can drill into the saddle slot to use a jig for positioning the piezos on a pinless bridge.
Also, check out the instructions at the bottom of our installation guide here.
