First there was a ukulele, then someone made a ukulele that looked and sounded like a banjo - banjo-lele, then came the homemade version with a can of sorts - hence can-jo-lele.
Here is an early picture of my own go at a canjolele - tenor with a kauri neck and fancy former fancy biscuit tin hex body (top left in the photo). I wanted to try a tenor to give the podgy fingers a bit more fret space and it is a fair bit bigger than the concert size cigar box uke. The key design difference apart from the body type, is the neck running straight through the body to take string pressure of the flimsy tin. More to come on this one soon as I iron out some wrinkles with the sound.
