Open up your cigar box. On each of the shorter edges, find the center point and then measure 3/4" in each direction from this point.

Note: This is assuming your 1 x 2 is 1-1/2" wide. Adjust these measurement for the exact length of your 1 x 2 if need be.

Where you have made your marks, cut down until you have made two square holes that are flush with the top of the case that are the size of your 1x2.

On one end of your 1 x 2 make 4 sets of lines that are an inch apart, starting half an inch from the edge.

On the first line, make a mark 3/8" from the right edge.

On the second line, make a mark 3/8" from the right edge and 3/4" from both edges.

On the third line, make a mark 3/8" from the left edge and 3/4" from both edges.

On the last (fourth) line, make a mark 3/8" from the left edge.

Drill six 1/4" holes through the 1 x 2 where you had just marked.

At the opposite end of the 1x2, make three marks that are 3/8" apart (at 0.375", 0.75" and 1.125"), and that are 1/2" from the edge of the beam.

Drill through the 3 marks that you just made with an 1/8" drill bit.

Carefully pry off the back of your Radioshack buzzer.

Break apart the buzzer case without damaging or bending the piezo disc to free it.

You should be left with only the piezo disc with two wires attached.

Attach a black wire to the ground lug of the audio jack and a red wire to the signal lug.

With the potentiometer knob facing upwards and the three side pins facing you, wire the black audio jack wire to both the pin on the left and the case of the potentiometer. Also wire the black wire from the piezo disc to this left pin.

Wire the red wire from the piezo disc to the right pin of the potentiometer.

Finally, wire the center pin on the side of the potentiometer, to the closest (front) pin on the bottom of the potentiometer. Wire the red wire from the audio jack to the furthest (back) pin of the potentiometer.

Drill a 1/4" hole 1-1/2" from the bottom left corner of the cigar box for the potentiometer. I also drilled an 1/8" hold just to the left of this hole for the potentiometer's mounting tab (this helps the potentiometer lay flush with the case and prevents it from shifting).

Flip the cigar box on its edge so the clasp is facing upwards and drill a 3/8" hole for the audio jack near the potentiometer hole. Make sure not to put this hole too close to the top or bottom of the cigar box, or the audio jack won't be able to fit in.

Epoxy your 1x2 to the inside-top part of the cigar box.

Make sure that the end of the 1x2 with the three small holes is sticking out about half an inch from the cigar box on the side with the potentiometer hole.

Once the epoxy from the last step has set and your guitar can be handled, close the case.

Mix up some more epoxy.

Glue your 3" section of half round to the front of the cigar box towards the edge with the potentiometer hole.

Glue the 1-1/2 section across the length of the top side of the 1x2 about an inch from the holes you drilled there.

Thread a nut all the way to the bottom of the eye bolt. Put a washer atop this nut. Pass the eye bolt from bottom to top of the single 1/4" hole closest to the edge of the beam. Place another washer onto the eye bolt and fasten it all in place with a wing nut.

Repeat this process on the center hole in the second line and the left-most hole in the third line.

In short, each bolt should have a hole directly in front of it once complete.

Insert the potentiometer into the cigar box and fasten it in place with its mounting nut.

Next, insert the audio jack and fasten this as well.

Finally, using standard two-sided tape (preferable), attach the flat side of the piezo element to the underside of the front of the cigar box guitar. Try to place this close to the 3" section of half round that is glued atop.

Tie a guitar string to one of the small nuts.

Repeat the process with the remaining to hex nuts.

Keep track of which string is which. I highly recommend using the high E, B and G strings, as they will add the least amount of tension.

Pass the high E string up through the small hole nearest the potentiometer. Pass it along the length of the guitar and then down through the hole in front of the corresponding hardware tuner. Tie the end of the string to the eye bolt and twist it until the string is tensioned.

Repeat this in the center for the B string and then again for the G string.

Once all of the strings are tensioned, you can tune them to your liking.

Fasten a knob to the potentiometer to make it look finished.
