Cole Clark Ukuleles
Cole Clark are an Australian guitar maker who also have a range of ukuleles (called Ukelady). Most of their ukes are made from Australian Blackwood – from the same family of wood (Acacia) as koa wood.
As far as I’m aware, they are only available in Australia. You can find some for sale here.
Honey plays a Cole Clark UL1. You can see Bosko playing the same uke here.
