Kluson Troublebucker bridge humbucker pickup black. This one virtually goes to 11! The Kluson Troublebucker, built around a strong ceramic magnet, is tuned slightly more to the mid-range as its brother, the Kluson Jayscreamer. With a little more output and a savage bite, it is the pickup that lives up to its name at the bridge position: it makes trouble! The Troublebucker sounds fat but never swampy, it has punch, but with character!
