While the Felix guitar is a fun and wonderful novelty, it is first and foremost a real Martin guitar. And as with all Martin guitars, tone, playability, and quality are integral to its design.The body is a compact 0 size, similar to our traditional tenor design. An adjustable, modified low profile 14-fret neck (23" scale) was selected for easy playability. Gotoh Cosmo Black tuning machines with embossed C.F. Marti logo are chosen for precision and appearance.The Felix III makes use of Martin's highly advanced X technology, with textured HPL (high pressure laminate) one-panel back and sides. The top, also of durable HPL material, is reinforced with style Sitka spruce cross braces. Fingerboard and bridge are crafted of black Micarta, an excellent and environmentally friendly alternative to ebony. Nut and compensated saddle are shaped from black Corian and tusq material, respectively.
