The ACS combines classical guitar concepts with design elements of a solid body guitar. The Multiac ACS' incredibly comfortable neck, combined with a maple body and cedar top, help make it our most affordable synth access guitar. Although the body is chambered, the response of the cedar top is more typical of a solid body guitar than a traditional acoustic guitar. This design results in an instrument that is virtually feedback-free, making it easy to use even when playing at high volumes. The ACS and ACS Slim system includes individual transducers powered by a custom RMC™ preamplifier system. This system not only produces excellent amplified sound, but also produces a hexaphonic output via a 13-pin connector allowing direct access to RolandTM GR-Series guitar synthesizers.
