Cordoba are mainly a guitar company - specialising in nylon string acoustic guitars. Even though they have only been going since 1997, they have built a good reputation and have some very impressive supporters including Bon Iver, Leonard Cohen, Jose Gonzalez and The Decemberists.
They are based in the ukulele's original home Portugal (although the ukes are made in China), so perhaps not surprising that they also have a line of fine looking ukuleles. One slight area of confusion for me is what their 'koa' ukuleles are made from. They used to be advertised as being 'Portuguese Koa' - a wood which I couldn't find any reference to outside of these ukuleles and take to be an Acacia wood (a relative of the true Hawaiian Koa). However, they are now just referred to as koa.
