Details

There is a little bit of hidden magic within every Martin C-2 conversion, and this 1931 example exhibits the sought after tonality that only comes from a C-2 conversion done right.  The C-2 was originally a roundhole archtop  hybrid design produced by Martin in the early 1930s containing a carved arched top, paired with the back and sides of a flattop. The model never quite rose to prominence due to the tonal nature of its construction. Without the punch and power of a guitar with a carved back, and lacking the sustain and warmth of a flattop instrument, the C-2 was quickly forgotten about when Martin discontinued their archtop models during World War II.

It takes a skilled luthier to perform a proper C-2 conversion, ultimately converting the guitar into an OM-28. Due to the inherent design of its archtop origins, the neck is set at a steep angle to accommodate the carved top and tall bridge. In order to achieve a shallower neck angle, the part of the heel that joins the body must be fully reshaped. As a result, the fingerboard is shifted up towards the body a bit causing the neck to intersect the body between the 13th and 14th fret. Consequently, the bridge is repositioned slightly further from the soundhole than it would be on a conventional OM. As a result, these guitars are able to be intonated to a degree that surpasses the abilities of an original 1930s Martin guitar. 

The beautiful original Brazilian Rosewood back and sides of this C-2 were outfitted with a Red Spruce top, and an ebony belly-style bridge with a cut-through bone saddle.  The resulting instrument is an incredible one-of-a-kind OM-style Martin that predominately pre-dates World War II, yet can be purchased at a fraction of the cost of an original OM. This Martin C-2 Conversion has taken on a new life with a voice that is all its own, and it’s ready for countless more decades of making music.
