This is a simple guitar with no frills that can be built in an afternoon.

What we have here is a two string cigar box guitar that was given the name "Chugger" by Shane Speal. I used an Acid Blondie cigar box that most people understandably pass up when looking for a suitable guitar body since it is rather small. But it's deep and can produce some good sound!

Some screws, tuners, rivets, strings, and a hardwood dowel and you aren't far from a guitar.

As I stated in the vid, using the fret markings I give you is an approximation and not an accurate set of measurements to use for a fretted instrument. However, they are perfectly fine for a fretless/slide guitar.

Fret markings in the video are as follows:
1st: 1 7/16" or 3.65cm
2nd: 2 3/4" or 6.99cm
3rd: 4" or 10.16cm
4th: 5 3/16" or 13.18cm
5th: 6 5/16" or 16.03cm
6th: 7 5/16" or 18.57cm
7th: 8 3/8" or 21.27cm
8th: 9 5/16" or 23.65cm
9th: 10 3/16" or 25.88cm
10th: 11" or 27.94cm
11th: 11 13/16" or 30cm
12th: 12 1/2" or 31.75cm
