I bought a JJB prestige 330 passive guitar pickup from Ebay recently, and was so impressed I had to leave a review for it! I had researched acoustic pickups extensively on the net and had come to the conclusion that the best for my purposes was the K & K Mini, with 3 piezo sensors that you glue under the bridge plate. Only problem with that was the price! Then I saw the JJB Prestige 330 at almost half the price and thought I'd give that a try, based on many positive reviews I had read. I had it fitted professionally and was absolutely delighted when I tried it! No piezo quack, just the beautiful sound of my guitar (a Blueridge br160A) only louder. I highly recommend this pickup for any acoustic guitar player who wants superb amplification at a reasonable price!
