At 1:58 in this video, Alex Rosamilia says he replaced his SG pickup with a Seymour Duncan Seth Lover.

"As far as pickups I use Seymour Duncan. The pickups vary from guitar to guitar but usually consist of either Seth Lover, Custom Custom, or P.A.F style humbuckers. If I am using a guitar that has a tremolo then chances are that I will have my own model Trembucker (PA-TB3B) in it. The whole concept behind the PA-TB3B was to make up for what the guitar naturally loses when you route out the body and add a tremolo. Most guitars take on a thinner more anemic quality once they are routed out, so having a pickup that helps compensate for that is a huge benefit. In general, I tend to favor lower output pickups and let the amps and pedals do the work."

"The guitar has a Seymour Duncan Seth Lover in the neck position and Duncan Hot Rails at the bridge. I built it in 2006, I believe.” Mike ran straight into a Richard Goodsell Black Dog 50 connected to a ’80s Marshall 4x10 1965A cabinet."

“The Seymour Duncan pickups I use in Skindred allow otherwise stock guitars to cope with drop tunings, heavy riffs and such. I’m constantly on the quest to improve my tone, and I’m learning that I prefer the sound of ceramic bar magnets and overwound coils for tight low end and shredding, and chunky mids. Adversely, I also had Seymour Duncan Seth Lover and Pearly Gates humbuckers in other guitars I used for standard tunings and more straightforward rock n’ roll, and they are amongst the sweetest sounds out there if you’re looking for lower to medium gain tones. What’s coolest about using SD versus stock pickups is that most Seymours are 4-conductor wired for endless tonal versatility and variety.”

"Nathan: In my Jazz Basses, I have the SJB-1 Vintage set and in my P-Bass I have the SPB-1 Vintage. In my guitars I have a custom set of Seth Lovers in a Firebird clone, a set of Antiquity Humbuckers in a ’81 Gibson 335, a SJM-3 Quarter-Pound for Jazzmaster, and Phat Cats in another Firebird clone! Love ’em!!"
