Made just like our popular original Ultra-Cool SR series but with a fine sand textured coating instead of our nubby rubberized grip found on the original ULTRA SR series. This new material offers the buttery feel of a nylon pick with a super crisp attack exceeding that of celluloid. This style has a slightly warmer sound then the original ultra-cool SR series line. Clean & True to your guitar's own tone. Hear & feel it for yourself. Harmonically resonant micro-fiber technology is the key. It sounds like titanium, glass or similar resonant material!
