First of all I would say I was very impressed with the costumer service from BK. Tim was very helpful and the email response time was incredible. I ordered them on a Mon and they arrived in week, not bad from England to Canada and I was updated throughout the shipping. The set I ordered was the warpig set (ceramic bridge) for my Jackson soloist. The main complaint I had about the guitar no matter which pickups I put in it ( many duncans) is that it was lacking in the bass, bright and very thin sounding. Needed something to wake up the guitar, well the warpig not only woke up the guitar it pissed it off as well. The bass response, low mids and shear output of these pickups are incredible. But the best thing about these pickups and I was not accpecting this was the sustain. After 2 years of trying different pickups in this guitar I finally found the match. It's been 2 weeks and I do see these pickups ever leaving the guitar. Jackson should just put these in at the factory. Great service, great sounding pickups, I think BK got a costumer for life.
