This is another Blackwood soprano uke with an arched back. There is a page featuring a Jarrah arched back soprano here.
Another arched back soprano, this time with ebony fingerboard, at the owner’s request.
The uke below has a Wandoo fingerboard and my wax finish, with Aquila strings. It is incredibly responsive.
....and this one, made for a jeweller friend of mine, has rosewood binding and a gold and silver inlay made by the owner.
