I needed a pickup that I could easily install and remove from guitar to guitar—this is what I created with few spare parts I had laying around.

I grabbed a Lego crate and lid got the housing and a RCA jack for the connection. The active agent is a piezo disk that I broke out of a buzzer housing.

Drilled a hole in the bottom of the crate and installed the RCA jack.

Then, I drilled a hole in the  lid and inserted the piezo wires.

Next, I soldered the wires to the hot and ground terminals on the RCA jack and closed the crate.

To allow for easy installation and removal, I added a 3/8″ removable Glue Dot to  the back of the piezo disk and one side of the Lego Crate. Done.

It needs some more sound shaping, but it has potential and is decent in a pinch.
