The AC Series consists of thoroughly traditional classical guitars built in the timeless Spanish style. To maximize the vibrations of the strings and the body’s resonance, lightweight woods are used through an advanced manufacturing process for that timeless Spanish sound, feel and playability. These guitars produce a deep bass and a sweet high-end with a rich midrange that only sound better as the guitars age. For long-term stability, the AC Series guitars also feature a truss rod so the proper amount of neck relief can be dialed in no matter where you are located and what the climate is like.
