The Pure Mini is K&K's award-winning, signature pickup for steel string acoustic guitars. The Pure Mini is a 3-head, bridge plate transducer. It features super balanced, flat sound transmission, warm woody tone without any quack and superior dynamic range all over the guitar's frequency spectrum. Their customers tell them that the Pure Mini's output is louder than any other passive pickup on the market.
Bridge plate transducers are the optimal choice for achieving a rich, natural guitar sound. The Pure's position on the bridge plate provides the perfect balance of sound, picking up all the strings without sounding harsh or percussive and "listening" to the sound board to amplify the unique characteristics of your guitar. The result is a warm, full-range signal that sounds great even without a preamp!
Although I haven’t tried it yet, I’m sure I’ll love it...a friend has one in his old Gibson and I bought this for my old J-45...
