Historically, 21 styling has represented the most simple appointments offered with rosewood back and sides and a spruce top. The OM-21 Special closely replicates this plain but beautiful style by blending rosewood bindings, a fine patterned Herringbone rosette, a nitrate tortoise pickguard and ebony fingerboard and pyramid bridge. The result is a stunning guitar that pays homage to the Golden Era styling.

amazing guitar!!!!

By Brandon Lanning

from Dayton, Ohio

I recently received one of these guitars. I have tried out hundreds of acoustic guitars and none come close to having the dynamics of this guitar. The only thing that came close was a Collings, which are twice the price. This thing is perfect, the only thing that I can think of that people who use open tunings without a capo will not like this guitar. The bracing in this guitar is super light and brittle and cannot withstand tuning your strings up and will snap the bracing. So tune down and use a capo! other than that this guitar is simply amazing..

OM-21 Special is a feast for the senses.


from Woodland, California

My new OM-21 special acoustic guitar is the most beautiful, magnificent guitar I have ever owned. It replaces another OM-21 that was stolen from my home. I loved that guitar, and thought I would never find one I could love more, but I have. This guitar sounds wonderful, feels wonderful, looks beautiful, and even smells inspirational feast for the senses. Everything written about it is is a "stunning" guitar in every way.
