After many in depth emailing between us, Mr. John Kennedy of Pulp Logic delivered an absolutely stunning set of three Jazz bass pickups for my Chris Stambaugh made Space Bass. His unique pickups were housed inside spalted maple covers, which beautifully complimented the top wood of my bass. John is a TBer and I became aware of him with this thread: http://www.talkbass.com/forum/showthread.php?t=555487&highlight= I purposely installed these pickups to hear how they would sound with the onboard preamp (East UK BTB-01) in the same settings as the originally installed EMG J pickups, it was immediately obvious that these pickups were not merely just EMG clones. I now have to cut back both bass and treble from their original settings. Without doubt, John's pickups have a very broad frequency range, much wider than the EMG Js. Personally, I like the sound of EMG pickups, but feel they sometimes have the tendency to make all onboard preamps sound the same, not with these pickups. These pickups have the clarity of EMGs, but with the character of lets say, DiMarzio Ultra Jazz(ish). It is also my opinion that these pickups sound more like single coil pickups than the EMG Js. I couldn't be any happier with the sound and looks of these pickups. Plus, John is absolutely a class act with first rate customer service. He was able to decipher my cryptic (and often childish) description of tone that I was searching for. I strongly suggest contacting John and chatting about your perfect tone, if you're not satisfied with your current pickups. This man has absolutely nailed the tone I requested in all three of my pickups. I can't express enough how happy I am with the tone of these pickups! At last, I'm finally satisfied with the tone of this bass!
