What a Cigar Box Guitar Is
A cigar box guitar is a simple stringed instrument using a cigar box as the resonating body. Three strings tuned to GDG or open G (GBD) are played with a slide. The neck is typically a 1x2 or 1x3 piece of oak or maple, and the box provides acoustic amplification. Most builds also add a simple piezo pickup for electric amplification. The playing technique — slide guitar — requires no fretting and produces a raw, expressive sound associated with Delta blues.

Prepare the Cigar Box
Reinforce the box and drill the string holes and pickup cavity.
Prepare the Cigar Box
Choose a hardwood cigar box — thicker lid produces better resonance. Reinforce the interior corners with small wood blocks glued in place. Mark the position for the neck to pass through (centered on the short end). Mark the bridge position at the correct scale length (typically 24 to 25 inches from nut to bridge). Drill a small hole for the piezo pickup wire at the bottom.
Cut and Shape the Neck
Saw the neck blank, mark fret positions, and route or carve the truss channel.
Cut and Shape the Neck
Cut a 1x2 piece of oak or maple to 30 inches. The neck passes through the box (neck-through construction). Mark the nut position at the top and the heel position where the neck exits the box at the bottom. Shape a gentle taper from the nut to the heel with a hand plane or spokeshave. Sand through 220 grit. Three-string CBGs do not require a truss rod — neck relief is not critical.
Install the Neck and Set Scale Length
Glue and clamp the neck through the box, confirming scale length.
Install the Neck and Set Scale Length
Confirm the scale length (nut to bridge = 24.75 to 25 inches). Apply wood glue to the neck where it contacts the box interior. Insert and clamp. The neck should fit snugly — shim if needed. Let cure 24 hours. Install nut and bridge: the nut is a small piece of bone or hardwood with three notches; the bridge is similar. String height (action) at the bridge: about 3mm for slide playing.
Wire the Pickup and Install Tuners
Solder the piezo disk to a 1/4-inch jack, install tuners, and string up.
Wire the Pickup and Install Tuners
Glue a piezo disk element to the inside of the box lid. Solder the piezo center to the tip lug of a 1/4-inch mono jack and the piezo ground wire to the sleeve lug. Mount the jack in the box. Install 3 open-back guitar tuners on the headstock. String with standard acoustic or electric guitar strings: low E, B, and G (strings 6, 2, and 3) are common choices for GDG.
Parts List
Hardwood cigar box — lid should be solid wood
30-inch piece of 1x2 oak or maple for neck
3 open-back guitar tuners
Piezo disk pickup element
1/4-inch mono output jack
Bone or hardwood for nut and bridge
Guitar strings — low E, B, G
Wood glue, sandpaper, finish
Slide Guitar Needs High Action Unlike fretted guitar which needs low action, slide guitar plays better with 3mm or more at the bridge. The slide rests on top of the strings — it does not fret them. If action is too low, the slide buzzes against the frets. Many CBG builds have no frets at all, which actually simplifies construction and suits slide playing.
