Slash

Slash uses the Seymour Duncan Alnico II Pro Slash Signature Pickups for their medium to low output, which provides a gruff tone distinct from high-output pickups typically associated with heavy metal. This is detailed on Slashparadise under the section "Slash's Accessories."

Almost all of Slash Les Paul are equipped with Seymour Duncan Alnico 2 Pro pickups.

The Seymour Duncan Zephyr Silver Humbucker, ZS-1, is listed on Slash's profile on the Seymour Duncan website, indicating his association with this gear. Further details on which specific guitars he uses them with are not provided.

Slash used the Seymour Duncan Alnico II Pro neck and bridge humbuckers in all his guitars, prior to the development of his signature pickups which are based on them.

According to Fishman Slash is using this pickup on acoustics.

In a video from the official Seymour Duncan YouTube channel, Slash discusses his new signature pickups, the Seymour Duncan Slash 2.0 Signature Humbuckers. These pickups provide a higher output compared to his previous signature models, achieving increased volume and drive without distorting or altering the PAF tone that Slash is renowned for.

This set was originally commissioned by Slash for the Guns N’ Roses performance at the Back to the Beginning tribute to Ozzy Osbourne, where Slash rocked a pair of his 3.0 ’buckers. In his own words, the Slash 3.0 set “is basically just one more step up. You have more output, but still that same clarity and honesty of the sound of the guitar.”
