I have tried a lot of different makers (including Fralin, Tom Holmes, SD, DiMarzio, PRS, Gibson's Classics and EMG's). I had seen the same thing as Heyden, in that the newer pickups didn't compare to the originals (SD and PRS are the ones where I noticed the most change). I saw an ad for the Crawler, and I always like Geoff Whitehorn's sound, so I called. Once I spoke with Tim I was really impressed with his philosophy and his knowledge of sounds. I ordered 2 sets and I was hooked! One year later and I have BK's in about 15 guitars!
