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. MGM currently has one for sale in his store. 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 regularly turn out unusual and interesting cigar box ukes.
