The Martin OMCPA4 Orchestra Acoustic-Electric Guitar is constructed with solid tonewoods. The back and sides are matched from African sapele, similar in appearance and tone to mahogany. Bookmatched Sitka spruce soundboards utilize Martin's Hybrid "A-Frame" scalloped bracing.
The OMCPA4 features a slim, more parallel taper at the 12th fret, allowing for a more comfortable playing width up the neck. The bridge spacing is also modified to 2 3/16" – splitting the difference between Martin's two traditional spacings.
Along with the look, feel, and enhanced performance of Martin's existing Performing Artist Series models, the OMCPA4 also has the new, simplified Fishman F1 Analog electronics system.
