The models are easily explained.
There are four different body shapes:
AD - is a Roundshoulder Dreadnought
The ASP (P=Performer) is a stage guitar and has the same body shape as the AS, but with reduced body depth and optional Fishman pick-up.
The ASN model is a nylon string guitar and has the same body shape as the AS, but with a slotted headstock and a slightly wider finger board (prices on request).
There are several choices of tonewood for the body, and each can be delivered either with spruce or cedar top.
