This is a pack of twenty-five (25) unwired "mini" piezo disks with an outide diameter of 12mm (0.47 inches). This smaller size is good for embedding these piezos in bridges and other uses where overall size is a concern. These can be installed in cigar box guitars, foot stompers and other home-made instruments, and can also be used as drum triggers. They can also be used for custom pickup arrangements in more traditional stringed and percussion instruments. 

An electric pick-up is a sure-fire way to take your cigar box guitar or other build to the NEXT LEVEL, and many builders report that their instruments are much more attractive to potential buyers if they include a pickup. So here is your chance to take the plunge without dropping a huge wad of cash!

These piezos can be easily wired with leads using very basic soldering skills. Simply use good-quality solder meant for electronics work and fairly fine wires (24 or 26 gauge); solder one lead to the brass portion of the disk, and one to the ceramic portion. It works best if you drip a small drop of solder onto each location first, let it cool, then press the wire into it with the soldering iron until the solder accepts the wire. Don't blow on the solder to cool it, as this makes the bond weaker.
