It all started when I was disassembling the last pieces of a parade float we had built a few years ago so our grand kids could ride in a parade. The float resembled a steam boat and there were two oak spacers between the smoke stacks. I could not bring myself to throw away the two pieces of oak. They looked as if they would make good cigar box guitar necks. I like the idea of making something from found stuff and junk from around the garage and house. The original oak pieces were sawn from a junk oak shelf. To see the two oak pieces acting as spacers between the smoke stacks, check out the  following steam boat video.

Some pieces I am using are not junk and found stuff.  The tuning machines, cigar boxes, strings, and bridges were purchased from Amazon and CB +Gitty. If a traditional three string instrument is being built, you might as well build two and buy a regular set of 6   tuning machines. I am building two.  I do not have the patience or skill to build a fretted neck so the two instruments will be slide only.  The distance from bridge to the nut ( the nut is really a bolt ) is 25″.  Each instrument has two piezo pickups, a disk type on the sound board and a rod type in a ukulele  stile bridge.  See the schematic below.   After reading Merlin Blencowe’s preamp book and discussing things on the AX84 Forum.  I learned that Piezos should look into at least 10 Megs. So the preamp will have an input impedance of 15 meg. and a voltage gain of  10.

 Baritone on left, tenor on right.Units are tuned and playable as acoustics, but no electronics installed at this time. 

For lack of better names, one CBG will be called a baritone, and the other a tenor.  The cigar boxes are slightly different in shape, both were rapped with a knuckle and the one with lowest sounding thump became the baritone.  The strings used on the baritone are regular guitar strings.  The tuning is:

G2   97.999 cps.

D3   146.83 cps

G3   196.00 cps

For the G2 string a regular guitar E2 string was tuned up to G2,  For D3 and G3 The regular guitar strings were tuned as they would be on a guitar

The tuning for tenor is:

G3   196 cps

D4   293.665 cps

G4   391.995 cps

This tuning range is too high for regular guitar strings especially the G4 so a special set by Southbound String Co was purchased from CB Getty.
