I really don't want to sell this one, but I'm just not playing it like I thought I would...
The GL-1 is a combination of a tenor ukulele body and a small-scale classical guitar neck. It uses standard classical guitar strings and is tuned A-D-G-C-E-A, which is the same as a guitar capoed at the 5th fret. The tone is quite pleasant, and you can get an idea how it sounds by finding some of the videos on youtube of people playing guitar arrangements of things like Bach pieces.
The case is a very good quality Oscar Schmidt item, and is like new because I bought it in case I wanted to take the guitarlele someplace, but never did.
Price is firm for this item, and at least for now I'd prefer to sell the instrument and case together.
