Fishman once again breaks new ground with its trademarked Smooth™ acoustic compression circuit, an essential feature of their new top of the line preamp, the Pro-EQ Platinum™.

Designed in response to requests from musicians for an easy to use preamp that incorporates a DI, the product's basic feature set was modeled on the company's own Prefix Plus™ Onboard Preamp. In addition, the new compression circuit softens and subdues what some acoustic aficionados refer to as a brittle, high frequency "quack" that may emerge when strings are hit hard. At the same time, the technology is transparent to the delicate, high harmonics characteristic of fingerstyle guitar.

Other indispensable features are a balanced XLR output, pre-EQ/post-EQ switching and ground lift. Long battery life is insured with low, current drain electronics. The Pro-EQ Platinum™ sports a road-rugged design housed in a high-style injection molded case of tough, high impact, automotive-grade resin with convenient battery access. The Pro-EQ Platinum™, the next revelation from the engineering minds at Fishman.

The Fishman "Matrix" may well be the most transparent under the saddle pickup on the market. Those with a discerning ear will find little lost when the guitar is not plugged in ( a fear among many who don't want anything under their saddle). A number of fine pre amps also.
