Easy fit. Great sound. Don't be put of by the fact this is a "magnetic" pickup! Played through any dedicated acoustic amp or PA it sounds incredible. The M1 Active takes the M1 pickup to a new level of performance and convenience. The built-in all class A electronics eliminate the need for any external preamps and makes the M1 Active compatible with any outboard equipment. And the new volume control gives you fingertip access in any performing situation. R$299
