How
Based on these Make Magazine projects. Guitar and Amp
Parts
Guitar
| Part | Quantitiy | Notes |
| Cigar box | 4 | |
| 1×2 oak or maple lumber | 0 | 3' length The actual dimensions are 3/4"×1 1/2". A 6' stick, enough for 2 necks, Pick the straightest, flattest, clearest, meaning free of knotholes, piece you can find. |
| Guitar strings | 0 | Standard medium-gauge strings work well. CBGs typically use open G tuning. I use strings 5, 4, and 3 and tune them to G-D-G. |
| Tuning pegs | 6 | 1 Pack of six individual heads |
| Fret wire | 9feet | Figuring 2inch width on neck, 24 frets, 2 guitars plus a bit extra |
| Cabinet hinge | 0 | with 3 mounting holes on each side |
| 1" wood screws Phillips head | 0 | |
| Bamboo barbecue skewer or other hard, thin rod | 0 | for the bridge and nut |
| Super glue optional | 0 |
