Picture of Electric Cigar Box Guitar

Albeit guitar manufacturing has come a long way in the past hundred years, there is a long history to show that you don't need much to make a guitar. All you need is a box to resonate the sound, a plank of would to act as the fretboard, a few screws, and some string. On account of its simplicity and instant reward factor, it is still pretty fun to build one of these traditional homemade guitars.

Yet, it would be a little silly to ignore all of the great things that have happened to guitars in the last hundred or so years. With this in mind, we are going to be bringing this cigar box into the modern era by amplifying it with a piezo contact pickup and a volume knob.

Step 1: Go get stuff

Picture of Go get stuff
You will need:

- 10K-Ohm Audio Control Potentiometer with SPST Switch (Model: 271-215 | Catalog #: 271-215)
- 90dB Piezo Pulse (Model: 273-066 | Catalog #: 273-066)
- 1/4" Mono Panel-Mount Audio Jack (Model: 274-255 | Catalog #: 274-255)
- a cigar box
- 3 feet of 1x2
- 1-1/2" section of half round
- 3" section of half round
- (x3) 1/4" x 3" eye bolts
- (x3) 1/4" wing nuts
- (x3) 1/4" nuts
- (x3) 1/4" washers
- nylon guitar strings
- 5-minute epoxy

Step 2: Measure and mark

Picture of Measure and mark
2B.jpg
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.

Step 3: Cut

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.

Step 4: Measure and mark

Picture of Measure and mark
4B.jpg
4C.jpg
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.

Step 5: Drill

Picture of Drill
5B.jpg
5C.jpg
5D.jpg
5E.jpg
Drill six 1/4" holes through the 1 x 2 where you had just marked.

Step 6: Measure and mark again

Picture of Measure and mark again
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.

Step 7: Drill again

Picture of Drill again
8B.jpg
Drill through the 3 marks that you just made with an 1/8" drill bit.

Step 8: Piezo

Picture of Piezo
9B.jpg
9C.jpg
9D.jpg
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.

Step 9: Audio

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

Step 10: Wire it up

Picture of Wire it up
11B.jpg
11C.jpg
11D.jpg
11E.jpg
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.


Step 11: Drill

Picture of Drill
12A.jpg
12C.jpg
12D.jpg
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.

Step 12: Glue

Picture of Glue
13B.jpg
13C.jpg
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.

Step 13: Glue more

Picture of Glue more
14B.jpg
14C.jpg
14D.jpg
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.

Step 14: Tuners

Picture of Tuners
6B.jpg
6C.jpg
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.

Step 15: Install

Picture of Install
16B.jpg
16C.jpg
16D.jpg
16E.jpg
16F.jpg
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.

Step 16: Tie

Picture of Tie
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.

Step 17: String it up

Picture of String it up
18C.jpg
18D.jpg
18E.jpg
18F.jpg
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.

Step 18: Finishing touch

Picture of Finishing touch

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

i have to try make these, thanks the elecrtric cigar box guitar look great

marrymay6 months ago

If this is possible to make it able to chain with the effect pedals? Ha...if that's ok, I am sure that i will go with a distortion guitar first!

Could you possibly provide a video clip or a sound clip?

Ninjakaib2 years ago
How much would it cost to make this?
Depends on what materials and "extras" you choose.
Just use the checklist provided and use Google to start a basic search to get an idea.
randofo (author)  Ninjakaib2 years ago
Not much. $20 - $30 at most. Probably less.

It's nice not to glue down the bridge part (the wooden part down where you first insert the strings, with the 3 holes). This will allow you to slide it about to make sure you get the correct pitch. Estimating on a fretless where a note should be will be much easier if the guitar's intonation is correct. Some folks never glue their bridge down. Cutting slots for the strings to fit/guide into would also be good for the bridge and nut.

I am just finishing my first build and about to start a second (just like this one shown in this 'ible).

Great choice for a cigar box, man!
Love the look of that one.

I'm confused because your directions for wiring don't match your pictures or video and the pictures of the wirings don't even match the video of the wirings. In the pictures, you don't show wires on the middle terminal of the pod or on the back prongs and in your video you have red wire on the left terminal and black on the right when in the picture it's opposite. Am I just misunderstanding something.
There is no wire going to the middle lug on the pot--it's grounded. It needs to be bent back and soldered to the flat surface of the pot.
Just Google "guitar wiring diagrams" and pick the 1 pickup diagram.
randofo (author)  pianoman231 year ago
Go by the pictures and text, not the video. I am pretty sure the picture matches the text. What exactly are you confused about?

This is a FANTASTIC tutorial, and you made a fine looking CBG. I like that you went with anon-paper covered cigar box--it adds class to the guitar.

My question/concern, is why you went with a 10K Ohm pot. A 10K pot really limits your range. For anyone else building a CBG--please go with a 500K or even a 250K Ohm pot. Make sure it's an audio(log), too--not a linear taper.

So if i were to wire it the way you wired it will the on off switch in the pot still work?
The pot more than likely works as a volume...

I know nothing about guitars; does the cigar box dimensions affect the sound? Do I need to keep within any particular range of dimensions? thanks
Yes, smaller the box, smaller the potential resonance and sound. An average box at the local cigar shop should only be a few bucks. I think I paid $3 for the one I made above and $1-$2 for a smaller paper covered, wooded, Punch box (those being the average size, like the one in this 'ible).

Just finished building one and I can't be happier. I have mine tuned to D F# A at the moment w/ the (GBE nylon strings). It stays in tune for the most part, but I still need to let the strings break in.

You actually want to get 6 1/4" washers as they tell you to put one on the back and front of the headstock for each eye bolt. Being out of washers, I fashioned some from an old bread pan, it's quite classy :) It's also nice to have things like random files, a coping saw and some good clamps help the process.

Other than that, I drilled into the bridge side for my jack and used a spade bit to widen the hole enuf so I could fit it in. It makes sense to put it on the bottom, but I like it on the side. I taped my piezo right under the bridge on the bottom of the neck.

It turns out feeling like a 3-string diddley bow to me, but I could see how lowering the bridge and nut down and adding frets would produce a different instrument altogether.

For fret markers, I have been using stickers and then taping over them with clear packaging tape. It's easy and that's all I really need.

This site helped me setup the wiring for the guitar. Use alligator clips to replicate it then check it with an amp to see if everything is working right before you solder it in.
Add one more string and you would have a ukulele! Nice job by the way.
I got myself the cigar box and had taken a electric kiddy guitar apart for some hybrid combonation guitar. now you ible has inspired me to use the volume pizeo and audio jack method you describe here . great resuilts youi got. mine is all flexable the part with two by one showed me how to over come that problem. and i was trying to figure out the way to get tensioners this just fixes alot doughts i was having gee wiz thanks . I passed on a mini amp i could got for two buxcks it fit so well right in the box maybe its still there hopefuly it had two AA battery box mini amp n flat speaker

Cigar box guitars have been getting popular recently, I've noticed. Very nice instructable! My dad is going to like this.
Redgerr REA4 years ago
getting popular where? O_o
Phoghat Redgerr3 years ago
Long answer...Yes Try http://www.cigarboxnation.com/  for more information. They also sell kits, offer advice, etc.
REA Redgerr4 years ago
well, i know alot of people are starting to buy and sell them around here.

Nice pictures! I like the video. By the way, do you know if you can do this without electric additions, would you need acoustic sound holes or what?
Long answer...Yes Try http://www.cigarboxnation.com/  for more information. They also sell kits, offer advice, etc.
randofo (author)  Booratman3 years ago
No acoustic holes required, but I suppose they could not hurt.

Do you know if a cigar box could support a fingerboard along the neck?
Long answer...Yes Try http://www.cigarboxnation.com/  for more information. They also sell kits, offer advice, etc.

I have your book! this looks like an awesome project...
what dose the pot do?
randofo (author)  Jr Hacking kid3 years ago
It controls volume
where are you guys getting cigar boxes?
randofo (author)  egallagher-doucette3 years ago
I got mine from a cigar shop. They often have extra boxes lying around. You have to ask. Sometimes that might charge you a small fee for them.
Artkid19763 years ago
I'm talking about the potentiometer.
Artkid19763 years ago
Great info, but the photo of the wiring is incorrect. The side mount should actually be the middle mount on the bottom with the others. Not sure if that makes sense.
mrmerino3 years ago
those are the exact piezo and jack i used to make a pickup for my acoustic guitar.
