Seymour Duncan SSL-4, famous for being on Ritchie Blackmore's Stratocaster. It's known for its thick sound, unlike typical single-coil pickups. I bought it new from Sound House this year, but I'm selling it because I sold the guitar I planned to put the pickup on. The outer box has had the seal removed, but the contents are in the same condition as when I bought it. Seymour Duncan's Quarter-Pound for Strat pickup provides high output and clear sound quality. - Model: Quarter-Pound for Strat - Brand: Seymour Duncan Please refrain from negotiating the price.
