The MF is a satin finish F-model with simplified appointments. With a fully carved Adirondack spruce top and maple back and sides, the MF is built with the same quality construction as our fully-appointed models. These instruments produce the rich, woody tone that one would expect from a professional quality mandolin at an affordable price. Collings MF Mandolin Ivory Bound and Gloss Top. Collings hard case and pro set up included.
