Here for sale we have a MDO-305 Octave Mandolin. This modestly priced Octave mandolin in packed with quality: all solid woods. This Octave features a solid spruce top and solid maple back and sides, a 12" fingerboard radius 1 3/8ths nut. All in all, we feel this is one of the best octaves in this price range out there - and it comes with a gig bag to boot.
