GODIN MULTIAC GRAND CONCERT DUET AMBIANCE The Multiac Grand Concert Duet Ambiance features state of the art custom electronics by Fishman, that allows the player to select between 4 individual mic settings. Choose between these blendable sound imaging mics via the 4-way selector switch. Similarly to other Multiac Grand Concert models, the guitar's design unites a larger body with a Solid Cedar top and a neck that joins the body at the twelfth fret. The 2" width at the nut is slightly larger than the standard Multiac and more typical of the classical tradition. The result is the ultimate guitar for classical players that require amplified sound.
