I have been trying to get the specs for the LP Sig pickup with not luck. But it seems very likely that it is very close to the Triumph pickup.
A while ago someone of this awesome forum told me the pickup on the LP Signature is actually closer to the lo-z guitar pickups from that era.
It does make sense, as the guitar pickups are smaller and don't have the eight leads coming out the backside.
The impedance choice is made with the transformer rather than directly from the coiltaps. Just like the LP Sig and JCS.
This picture of an early LP Sig shows a smaller guitar sized pickup which is clearly a lot smaller than the Triumph pickup that I have on my JCS.
But when I saw this picture it was the direct inspiration to get rid of the Electar and install the Triumph pickup.
(I didn't know it should have maybe been a guitar pickup) And I haven't regretted it one single second.
The only thing that I still need to do is mount lightweight Gotoh Res-O-Lites to cure the neck dive.
