I'm seeing it here, unless I misunderstood and theyr're talking about the set with SSL-6. I see SSL-2 calibrated sets being sold several places, included several Reverb.com sellers..

"If purchased as a calibrated set, the bridge pickup is wound slightly hotter for better overall balance between positions."
The Duncan website does mention later, that I noticed it may be referring to the neck and bridge being the same. But like I mentioned above, some reverb sellers are selling a SSL-2C calibrated set that claims the bridge pickups is wound a bit hotter. It all kinda confuses me. I do like the SSL-6 with the SSL-2's, but the '6 is a bit louder. If the "calibrated" set is just the SSL-2 neck that is in the bridge position, I'll oder one of them and see how it goes. If there is an SSL-2 bridge specific pickup, I'd like to get it because I already have the neck and RWRP middle.
