What You Need to Build a Cigar Box Guitar

A cigar box guitar is a real, playable instrument made from a wooden cigar box, a wooden neck, and steel strings. You can build one in a weekend with basic tools and materials that cost between $30 and $80. The cigar box becomes the body that resonates and amplifies the sound, the neck is a piece of wood you shape yourself, and the strings are standard guitar strings you'll tension across a bridge.

This is not a toy or a craft project that sounds bad—thousands of people play cigar box guitars in blues, folk, and punk bands. The sound is twangy and percussive, closer to a banjo than a full-size guitar, but it carries well and has character. You do not need woodworking experience or expensive equipment. A drill, a saw, sandpaper, and a screwdriver are enough to start.

Key Takeaways

  • A cigar box, a wooden neck blank, three to six strings, and basic hardware (tuning pegs, bridge, nut) are the only materials you need.
  • Drill holes for the tuning pegs and bridge, cut the neck to length, and sand all rough edges before assembly to avoid splinters and poor sound.
  • The strings run from the tuning pegs at the headstock, over the nut and bridge, and anchor at the tail block inside the box.
  • Intonation (whether the frets are in the right places) matters less on a cigar box guitar than on a standard guitar, so you can use a straightforward fret calculator or spacing chart.
  • Your first guitar will teach you what works—many builders make three or four before they dial in the sound and playability they want.

Choosing and Preparing Your Cigar Box

The cigar box is the heart of your guitar. Look for a wooden box (not cardboard) that is roughly 8 to 10 inches long, 5 to 6 inches wide, and 2 to 3 inches deep. Avoid boxes that are warped, cracked, or have soft spots. Cedar and mahogany boxes are common and sound good. You can buy new boxes online from cigar suppliers, or find vintage ones at thrift stores, estate sales, or antique shops.

Once you have your box, open it and remove any paper labels, tobacco residue, or loose material inside. Wipe the interior with a dry cloth. Do not soak it or use water—moisture will warp the wood. If the box smells strongly of tobacco, leave it open in fresh air for a few days. The smell will fade and will not affect the sound.

On the front face of the box, mark where you want the sound hole. Most builders place it in the lower half, off-center. Drill a hole 1.5 to 2 inches in diameter using a spade bit or hole saw. This hole lets sound escape and is essential for volume. Sand the edges of the hole smooth so they do not catch your hand when you play.

Building and Attaching the Neck

The neck is a piece of wood, usually pine or poplar, roughly 1 to 1.5 inches wide, 0.75 inches thick, and 20 to 24 inches long. You can buy a pre-made neck blank online, or cut one from a board at a hardware store. If you cut your own, use a handsaw or circular saw to get a straight edge, then sand it smooth.

Mark where you want the frets (the metal strips that divide the neck into notes). For a three-string guitar, frets are spaced roughly 1.5 inches apart at the headstock and get closer as you move toward the body. Use a fret calculator online or print a spacing chart and mark the positions with a pencil. Drill small pilot holes at each fret position, then tap in fret wire or use adhesive-backed fret markers. Many first-time builders skip metal frets and use tape or paint lines instead—this works and is easier to adjust later.

Attach the neck to the cigar box using a tail block—a wooden block glued and screwed inside the box at one end. The neck sits on top of this block and is secured with screws or bolts. Drill holes through the neck and into the tail block, then drive screws from underneath so they do not show on the playing surface. Make sure the neck is straight and level before you tighten everything down.

Installing Tuning Pegs, Bridge, and Nut

The tuning pegs hold and tension the strings. Drill holes in the headstock (the end of the neck farthest from the body) sized to fit your tuning pegs. Standard guitar tuning pegs have a shaft roughly 0.25 inches in diameter. Drill from the back of the headstock so the peg sits flush. Insert the pegs and tighten the set screws so they do not slip.

The nut is a small block of bone, plastic, or wood that sits at the base of the headstock and holds the strings at the correct height and spacing. You can carve one from a bone blank or buy a pre-made nut. Glue it to the neck with wood glue, making sure it is perpendicular to the neck and centered. Once the glue dries, use a file to cut small grooves in the top of the nut so each string sits in its own slot and does not roll side to side.

The bridge sits on the front face of the cigar box and transfers vibration from the strings to the box. It is usually a wooden block, 1 to 2 inches tall, with grooves cut in the top for the strings. You can carve one or buy a pre-made bridge. Glue it to the box with wood glue, positioning it so the strings run straight from the nut to the bridge without angling. Do not screw the bridge down—glue only, so it can vibrate freely.

Stringing and Tuning Your Guitar

Most cigar box guitars use three to six strings. Three-string models are the simplest and are tuned like the three highest strings of a standard guitar (G, B, E) or in an open tuning like G-D-G. Six-string models use standard guitar strings. Buy a set of acoustic or electric guitar strings—the gauge (thickness) does not matter much for a cigar box guitar, but lighter strings (0.009 to 0.046) are easier to play.

Thread each string through the tuning peg, leaving a few inches of slack. Wrap the string around the peg post two or three times, then pull it tight and turn the peg to wind the string. The string should wrap neatly without overlapping itself. Once all strings are wound, pull each one gently to stretch it, then tune to pitch using a tuner app on your phone or a clip-on tuner.

The strings anchor at the tail block inside the box. Drill small holes through the tail block or tie the strings around a wooden dowel glued inside the box. Make sure the anchor is solid—if a string slips, the tension will drop and the guitar will go out of tune. Tune up slowly, checking that the neck does not bend and the bridge does not shift. If the action (the height of the strings above the frets) is too high or too low, you can sand the nut or bridge to adjust it.

Adjusting Sound and Playability

Once your guitar is strung and tuned, play it and listen. The sound should be loud enough to hear across a room. If it is too quiet, check that the bridge is glued firmly and the strings are making good contact with the nut and bridge. If the sound is muted or dull, the box may be too thick or the wood may be too dense. Thinner boxes and softer woods (like cedar) tend to sound brighter.

If the action is too high (strings are far from the frets and hard to press), sand down the nut or bridge. If the action is too low (strings buzz against the frets), glue a shim under the nut or bridge to raise it. Make small adjustments—sand or shim a little, tune up, and play again. It takes a few tries to get it right.

If a string buzzes only on certain frets, that fret may be too low. You can tap it gently with a hammer to raise it, or file the neighboring frets down slightly. This is fiddly work, but it teaches you how the instrument responds. Many builders accept a little buzz on the first or second fret as part of the character of a cigar box guitar.

Common Mistakes and How to Avoid Them

The most common mistake is gluing the bridge down before the strings are on. Once the bridge is glued, you cannot adjust its position if the strings do not line up with the nut. Always dry-fit (place without glue) the bridge, string the guitar, and check alignment before you glue anything permanent.

Another mistake is using a cigar box that is too thick or too heavy. Thick boxes do not resonate well and sound dead. Look for boxes with thin walls (roughly 0.125 inches) and light wood. If you tap the box with your knuckle, it should ring slightly, not thud.

A third mistake is over-tightening the tuning pegs. If you crank them too hard, the strings will snap or the pegs will strip. Turn them slowly and stop as soon as the string reaches pitch. You can always tune up a little more, but you cannot undo a broken string.

Finally, do not expect your first guitar to sound like a factory-made instrument. Cigar box guitars have a raw, woody sound that is part of their appeal. If the sound is not what you want, write down what you would change (louder, brighter, warmer) and build another one with different materials or dimensions. Each guitar teaches you something.

Frequently Asked Questions

Can I use a cardboard cigar box?

No. Cardboard does not resonate and will not produce sound. You need a wooden box. If you cannot find a wooden cigar box, you can use a wooden jewelry box, a small wooden crate, or even a wooden recipe box—anything with thin wooden walls and a hollow interior.

How many strings should my first guitar have?

Start with three strings. Three-string guitars are simpler to build, easier to tune, and sound great. Once you have made one and understand how the parts work together, you can build a four-, five-, or six-string model. Many experienced players prefer three strings because the sound is clearer and the neck is narrower.

Do I need to know how to read music to play a cigar box guitar?

No. Most cigar box guitar players use tablature (tab), which shows you which fret to press on which string. Tab is easier to learn than standard notation and is freely available online for thousands of songs. You can also play by ear if you have a good ear for pitch.

What if the strings keep going out of tune?

Check that the tuning pegs are tight and not slipping. Make sure the strings are wound neatly around the peg posts without overlapping. If the pegs are old or worn, replace them. Also, new strings stretch and go out of tune quickly—tune up, play for a few minutes, tune again, and repeat until the strings stabilize. This usually takes an hour or two.

Can I paint or decorate my cigar box guitar?

Yes. Paint, stain, or decorate the outside of the box however you like. Just avoid painting the inside, where it will dampen the sound. Let any paint or stain dry completely before you string the guitar, and do not paint over the sound hole or the bridge.
