Kostal OM Cutaway Acoustic Guitar, Brazilian Rosewood & German Spruce - Pre Owned


Sold Make an enquiry


This absolutely breathtaking 2017 OM from master luthier Jason Kostal has absolutely stolen all our hearts here at TNAG. Built-in an outrageous set of flitch matched Master Grade Brazilian Rosewood for the back and sides and Master Grade German Spruce for the top, this OM has a crisp clean attach in the upper register, producing big phat (fat) trebles (we have grown to love from Jason's guitars), along with a subtle and pure bass response.

Overall a very well balanced and an incredibly versatile guitar, but definitely excelling at drop tunings such as Dadgad
