Look up Paul’s explanation videos about TCI technology. TCI is used to EQ each set of pickups to be consistent. It was also originally designed to relate to the SC594 neck joint and how it affects the guitar’s tone.
Copy. I don't understand the process either, but I recall him discussing how the TCI process accounts for the inconsistencies found between even "same batch" magnets, the sections of wire used, the phase of the moon, that type of sh!t...all in the interest of aligning each pickup's "whistle note". Explaining how it works is over my head.I get the aim, but understanding how it is done is where I gave up
What @bodia saidIt's not so much about the guitar, it's a process to make the pickups "match" better. Sure, they're designed and built by PRS, but that doesn't mean they can't go into other guitars. 58/15LT TCI can go into more than the 594, which is where they started (the LTs, not TCI, that was the Silver Sky). It's all about pickup consistency.
