The unique design of the Godin Multiac Grand Concert Nylon String Guitar unites a larger, chambered mahogany body with a solid cedar top and a mahogany neck with ebony fingerboard that joins the body at the 12th fret. The 2" width at the nut is slightly larger than the standard Multiac and more typical of the classical tradition. The Godin custom RMC electronics with 13-pin connector for direct control of Roland GR Series and Axon AX100 guitar synths will open up new musical contexts to the classical guitar player.
