My standard design is made in Amazon Rosewood for the sides and back, European spruce for the soundboard, mahogany neck, ebony fingerboard with tulipwood binding and herringbone purfling. It has a round soundhole and can be made strung in octave pairs on 3 out of 4 courses, or unison pairs throughout. The bridge is a floating type, with a tailpiece string fixing. This I consider produces a superior sound to the guitar type pin bridge found on some models. The tuning machines are Schaller M6 minis in chrome plate - the best on the market.
Cases are extra.
Both of these options have a tailpiece jack socket. Headway Electronics units are also available. Waiting time needs to be negotiated, depending on the other orders in hand. Alternative style instrument. This is the prototype I made for myself.
