Things You'll Need:
- Piezo buzzer element
- Wire strippers
- Soldering iron
- 1 1/4-inch audio jack
- 1 foot shielded audio cable
- 2 square inches medium density foam
- Hot glue gun
- Drill
- 1 3/8-inch drill bit
- Roll of electrical tape
-
Step 1
Open the buzzer element and extract the Piezo. The Piezo buzzer elements are made from two elements separated by crystals. It looks like a round, metal disk about the size of a can lid.
-
Step 2
Strip two inches off the end of the shielded cable. Solder one end onto the element. The ground wire needs to be soldered to the brass surface of the element. The positive wire needs to be soldered to the signal end of the element.
-
Step 3
Attach the audio jack to the element with the other end of the shielded wire. Solder the wires into place. Glue the small foam onto the back of the element. This improves the performance of the element.
-
Step 4
Mark a hole on the side of the guitar close to the guitar strap knob for the audio jack. Drill a hole through the guitar at this mark. For best results, remove the guitar strings beforehand. Drill the hole with a steady smooth motion. If you drill too fast, the guitar may splinter.
-
Step 5
Remove the washer and nut from the jack. Feed the jack through the hole in the front of the guitar to the hole you drilled. Use a magnetic wand to make this easier. Put the magnetic wand through the hole you drilled. Put the jack into the hole in front of the guitar until it meets the wand. Pull the wand out of the hole. Put the nut and washer into the jack to hold it into place, but do not over-tighten the nut.
-
Step 6
Hot glue the brass side of the element to the bridge of the inside of the guitar. Leave about half of the element unattached. Do not over glue. The thinner the glue, the better the performance. In most cases, the closer the element is to the bridge, the warmer the sound.
-
Step 7
Tape down the wires inside the guitar with thin electrical tape. Replace the strings and plug in the guitar.
