The Rusty King Mandolin – it is a 6-string electro-acoustic mandolin fitted with an excellent handcrafted humbucker pickup. 

The body was carved from a single piece of maple wood with a flame Ash top. The walnut fretboard was bound with strips of flame Ash. 

It also has an interesting feature - the G and D strings are single to make the bass lines a little more pronounced and less jingly.
