These have a very small output signal that makes me think the piezo element is tiny, tiny.

I bought these to make my own "western mini" type system. The small size is perfect. I soldered three of them to a pigtail that is now connected to a fishman prefix in my gretsch rancher Jr. Replaced a shot under saddle transducer. Coated the connection side of the discs with hot glue to protect them, then super glued them to the bridge plate using K&K's directions, and they work like a charm.

This purchase was very much so, easy on my wallet, and they were delivered faster then I expected. My only concern is that they arrived and despite my excitement and urgency to use them. They were very tiny and not capable enough for the application I bought them for. My advice for this seller is to put up a comparison photo of one or whole set of these in their hand or one next to a finger or thumb. That way others won't be a confused as I was. I still found an application for a few of these and are working great! Thank you again
