Introduction: Cigar Box Guitar

Usually consisting of a stick, an old cigar box, some random hardware, and whatever strings are lying around, cigar box guitars are some of the simplest, cheapest, and easiest musical instruments you can build.  They can have anywhere between one and six strings (although most have three), and pretty much any kind of tuning.

I decided to make a slightly fancier guitar than most, with real guitar tuning pegs, a nice stained and varnished finish, and a piezo pickup.  You might see some photos of my homemade banjo, since I built both around the same time.

A little history: cigar box guitars have been built since the time of the American Civil War, but they first took off in popularity during the Great Depression of the 1930s.  Blues musicians especially favored the small guitars, along with cookie tin banjos, washboards, and other improvised instruments.  During today's economic woes and the rise of the DIY and Maker movements, musicians and hobbyists have revived the art of building and playing cigar box guitars.

Step 1: What You'll Need

Supplies:

~Cigar box - $1
I got this one at a garage sale.  If you make friends with a cigar smoker or tobacconists you can probably get this for free.

~1" x 2" x 3" poplar board - $3
keep in mind that these are actually 3/4" x 1 1/2"

~Guitar tuning pegs (3) - $4
These usually come 6 to a pack for about $8, so you can make another guitar with the other three!

~Guitar strings (3) - Free!
I had some old nylon strings lying around, so I used the low E, A, and D strings.  You can also use fishing line, steel wire, or plastic string

~Copper sheet metal - Free!
This is used to make the tailpiece, the part that holds the strings on the bottom.  I found some while dumpster diving at a construction site.  You could cut apart a tin can if you can't find copper

~Wood glue - $3

~Wood stain (optional) - $4
You can use any color; I choose a reddish brown.  A little can'll do ya!

~Spray varnish (optional) - $5
I used semi-gloss.

~Piezo buzzer and guitar plug (optional) - $4
This gives you an electric cigar box


Tools:

~Hand saw

~Coping saw or jig saw

~Drill with bits

~Rough file or rasp

~Sand paper in various grits
I used between 60 and 400 grit, although 100 and 200 would work fine

~Clamps (or heavy things)

~Various hardware (screws, small finishing nails, etc.)

~Soldering iron (for connecting the piezo buzzer)

Step 2: Cut the Cigar Box

You will need to make several cuts in your cigar box.  First you will need to make a hole for the neck to pass through the box on one end.  My cigar box had a square end (where the hinges are) and a rounded end (where the clasp is), so I put the neck coming out of the square end.  There are several different kinds of cigar boxes, so you can figure out what geometry works best for you.

Once you've picked a side to cut, measure and mark the center of that side lengthwise.  Make marks 3/4" on either side of this mark.  Measure and mark 3/4" from the top of the box (or the bottom; whichever side you want to be the front of your finished guitar).  Connect these marks with a ruler to make a 1 1/2" by 3/4" rectangle, in the center of one side and right against the top of the box.  Cut out this rectangle and test fit the neck.  The hole should fit horizontally but be too small vertically by about 1/8", or the thickness of the top of the box..  We will account for this in the next step by cutting a notch in the neck.

Now it's time to cut sound holes in the top of the box.  You can simply drill some holes with a hole saw, but I wanted some stylish f-holes, like a violin.  First I printed off a picture of a violin and taped it to the top of the box, being careful to center it as well as I could.  Then I drilled out the top and bottom of each opening, and connected them using the coping saw.  A thin blade and a lot of patience helps here.  You can finish off any rough edges with a file or sandpaper.

Step 3: Notch the Neck

You will need to make a notch on one side of the neck so that the fretboard is level with the top of the box.  Measure the thickness of the box top and mark this depth on the top of the neck.  Measure the inside length of the box (ie the length of the box minus the thickness of one side) and mark this on the neck.  Then use a saw to make cuts of the right depth along the neck, and knock out the sections between with a chisel.  Test -fit the neck into the box and use a file or sandpaper to take away material until the fretboard and the top of the box fit flush.

Optional step: I added a heel where the neck meets the body, made from scrap pieces.  This is even with where the cutout begins, but on the opposite side of the neck.  I glued the blocks of wood to the neck and roughed out the shape with a saw and file after the glue dried.

You will also want to round out the back of the neck, to make it easier to slide your hand up and down.  This can be done with a rough file or low-grit sandpaper.  It doesn't have to be perfectly rounded, just smooth enough to be comfortable.

Now start sanding!  Especially on the back side of the neck, you want the wood to be very smooth.  I also wanted to make a nice and shiny guitar, so I went all the way up to 400 grit.  Unless you have a power sander this will probably take a long time.

Step 4: Carve the Tuning Head

First you will need to lay out where you want the strings, frets, nut, bridge, and tuning pegs on the neck.  I used another guitar to measure where I wanted the frets, but this fretboard template (part 1 and part 2, tape the two together)  would work if you don't have another guitar or if you want a shorter fretboard.

For spacing the strings, measure and mark every 7.6 mm across the neck.  You can calculate this with the following equation: string spacing = width of fretboard / (number of strings + 2).  Now you can start to lay out the shape of the head and the position of the tuning pegs.  If you have individual tuning pegs, you can make whatever shape of head you want.  With the three-in-line tuning pegs I have, I decided to do an angled head so that each tuning peg lines up with its respective string.  You could also use a violin-style tuning pocket.   See the picture below for a general view of the head layout I used.  Drill holes all the way through the head for the tuning pegs, being careful not to knock any chips out the back.  Don't be too worried though; the tuning pegs will cover up a lot of imperfections.

Now it's time to cut out the head.  I used an electric jigsaw, but you could use almost any kind of saw that is capable of making small-radius cuts.  Be sure to keep everything square and level.

Step 5: Stain and Finish

Stain or varnish aren't strictly necessary, but again I wanted a little bit nicer looking guitar.

After sanding you will need to wash off any sawdust before applying the stain.  Wet the wood with the stain thoroughly and wipe off any excess before letting it dry.

My guitar is fretless, but I used a Sharpie to add fret markers to the neck.  This wasn't the best choice, since the clear coat caused the lines to run a bit.  You could probably use some acrylic paint instead, or some countersunk nails to mark the frets.  There are many other ways of making frets if you want them; I've seen cigar box guitars with nails and wooden matches for frets.

Spraying on the clear-coat is best done in a well-ventilated area, and a face mask doesn't hurt either.  Hang up all the pieces with wire or string and add thin layers slowly to prevent runs.  When the first layer is dry you can wet sand with a high-grit sandpaper, then spray a second coat.

Step 6: Tailpiece

The tailpiece is the part on the very back of the guitar which holds the strings.  I made mine out of some copper sheet, but almost any kind of metal, or even a door hinge,  would work.

I used the same string spacing as on the neck and tuning head to space the three holes at the top of the tailpiece.  Then I scribed a symmetrical triangle with a pocket knife and marked another hole at the point.  After cutting out the triangle I rounded off the corners with tin snips and a file.  Then I punched out the holes with a nail.

Bend the tailpiece so that doesn't quite touch the top of the box, and be sure to de-burr the holes since sharp edges will lead to broken strings.

Step 7: Screwing It All Together (and Make It Electric!)

After test-fitting everything, glue the neck to the inside of the box.  Clamp it in at least two places with cardboard shims to prevent marks on the wood.  Drill a hole through the box and into the tail end of the neck.  Screw the tailpiece, the box, and the neck together.  Let the glue dry overnight.

Before closing up the box, attach a piezo pickup if you are using one.  This is really just a piezo buzzer from Radio Shack soldered to an output jack.  I'm not sure what the best method of attaching the piezo is, so I just nailed it in there with a couple small tacks.  You'll need to drill and countersink a hole in the box somewhere for the jack to pass through.  I keep the box closed with a few staples opposite the hinges so that I can open it back up easily, but you can also simply glue or nail it closed.

Screw on the tuning pegs and tie on the strings.  After you get some tension in them you can add the nut (at the top) and the bridge (at the bottom) and they will stay put without any glue.  Drive three small nails into the head right above the nut and hook the strings under the nail heads to provide downward tension on the nut.  I used a small nail for the nut and part of a bamboo chopstick for the bridge.

The tuning I prefer is D-A-D, or the bottom three strings of drop-D tuning.  Feel free to experiment with tuning, since there is no "standard" tuning for three-string guitars.

Step 8: Play!

Just as there's no "standard" tuning for a cigar box guitar, there's no official way to play it.  Feel free to mess around with tuning , making your own chords, etc.  Shane Speal has a series of videos (part 1, part 2, part 3) teaching some basics of cigar box guitar playing.  There are lots of other resources out there if you look.

Below are a couple mp3's to show what my guitar sounds like, and a video demonstrating some of its features.  At the end you can see my version of "Save Me" by Seasick Steve (who plays the blues with  his one-string diddley bow and his three string guitar).

I really dig the tail piece idea, its quite innovative and would make string changes a breeze. Also your idea of using a smaller nail (as opposed to large bolts seen in others) works best for me since I perfer a low string height. Overall great great great GREAT job! Out of all the instructables I've chosen yours to model my weekend build off.

i like this one
i have been collecting parts for three of the CBG and almost have everything i need but our are going to be acoustic and maybe upgradeable to electric
i am going to sit down with my two grand kids and we are each going to make one for our self selves
i think they mite like that and maybe be happy to play or make more instead of watching their games or TV
thanks for another instructable that will help me get this done

kgrant-2 made it! (author)kgrant-22011-03-21

At your Radio Shack store, there is a section with lots of drawers. The piezo buzzers are in one of those drawers. There are many differnt sizes and shapes. I used a piezo element, and other than my tuner doesn't like it, it makes a nice sound through my amp.

Thanks for the great instructable. I built mine over the weekend. Found a scrap piece of copper for $1, a box from a shop for $5, a 3" wide Poplar board for neck. I put the knuckle on mine as well. My son (project for him) loved it and was playing it all evening last night. I used a Radio Shack piezo element (not a buzzer, but an element), soldered to the jack. It sounds pretty good through my amp, but my tuner can't make heads or tails of the signal; it does not show the note when I pluck a string. I had to tune it by tuning my guitar to the right note and then making my CBG strings match by ear. Any idea why the piezo element doesn't work with my regular tuner?

I went to my local guitar repair shop and told the guy what I was building. He went in the back and four 3 pegs for me, $2 apiece. Must have been pulled off a guitar that was upgraded.

it would add stability to the neck. There will be a lot of tension pulling the neck upwards, and having another connection point to the box would be a way to get some strength. I would put a couple of screws into that heel through the inside of the box.

How are the strings in the tailpiece? It looks like you just tied them, but that can't be it. What am I missing? Thanks.

author
ricosgoo made it! (author)ricosgoo2011-01-06

Guitar strings typically have beads at the end of them. He probably drilled holes in the copper sheet and fed the strings through the holes. The bead at the end is too big to fit through the hole so it gets stuck there and holds in place.

You might want to use a wider neck (maybe 3") if you're doing six strings.  Daddy Mojo makes six-string CBG's for sale, but they aren't too cheap:

You could either carve down a larger piece of wood (like a 2"x4"), build it up out of smaller pieces, or use a 1"x3" like I did for my banjo neck.

I'm not finding your banjo instructable. Did you not make one for that instrument? I would be really interested in that. My kids are delighted with the instruments I've made, but they've all been rather ephemeral (read: flimsy) I'd like to make something like this for us to play.
What do you say? Even some pictures and an outline would be great!
Great build on this guitar too. Keep it up!

Just wondering, what's the sound quality if you plug it into an amp? is there a weird effect, or does it screech or anything?

author
discontinuuity made it! (author)discontinuuity2010-06-29

It sounds pretty good, but since it acts like a microphone it can pick up other sounds besides the strings. It's a bit buzzy too but I like the sound.

author
Frozen Twinkies made it! (author)2010-05-09

 When i turn on my amp (with the piezo and jack) it make a loud high pitched screeching noise. if i turn it down it stops and you can kinda hear the guitar sound but when i turn it up it screeches! PS i only took off the top plastic of piezo. matters?

author
discontinuuity made it! (author)discontinuuity2010-05-09

Not really sure.  You could have a short circuit, or you could have broken the piezo.  It could also be feedback, since the piezo works more like a microphone than a regular pickup.

author
Frozen Twinkies made it! (author)Frozen Twinkies2010-05-10

 So to reduce feed back, would i have to move it away from the amp?

author
discontinuuity made it! (author)discontinuuity2010-05-27

Yes, or turn down the volume.  Pointing the sound holes away from the amp will also help.

mattthomas992003 made it! (author)2010-04-14

what ends of the output jack did you attach your piezo to, I am having problems with that.

author
discontinuuity made it! (author)discontinuuity2010-04-14

It doesn't really matter, it will work either way. 

When the piezo vibrates it makes a vibrating electrical signal in the wire, ie positive/negative, on/off.  The amp amplifies this signal and outputs it to the speaker, making it vibrate at the same speed as the piezo. 

The only time that polarity really matters is when you're making a humbucker magnetic pickup, but that's a whole 'nuther story.

Mine are pretty cheap and cruddy, I think I paid about $13 at a guitar store for a set of six (or two sets of three, however you look at it).  I'd suggest going to the local music store and seeing what they have .

Please do.  There's not enough home-made instruments on Instructables, and no two are built exactly the same.

I should give some credit to Shane Speal and other CBG makers out there, but mine is rather different than Make's design.
