This project is my first electronics project I have done since high school where they taught me to solder things together. (However this is a skill that I seem to have forgotten as shown in my pictures.. being uploaded soon)

Basically what happens is the piezoelectric disc is stuck onto a surface (ie my guitar body) and it picks up vibrations on that surface. I then run the output of that through a preamp and into my guitar amplifier.

Project has been a fun, quick, easy build. If you have any ideas for other projects of similar difficulty please leave a comment.
