Cigar Box Ukuleles
Cigar box ukuleles may seem like a cobble together, homemade affair, but they have a venerable history and an expensive present.
Samual Kamaka made some high quality cigar box ukuleles. There have even been rumors that Leonardo Nunes's first uke was a cigar box uke (although John King said it was unlikely and I bow to his vastly superior knowledge).
The tradition of high quality cigar box ukuleles continues today, particularly with Black Bear Ukuleles who produced a number of unusual and interesting cigar box ukes.
