Like the standard APH-1 Alnico II Pro, which Slash has used for years, the Slash APH-2 set uses Alnico 2 magnets. However, the Alnico II Pro Slash is wound with just enough boosted output to push a stock Les Paul toward the sweet sustain and rude crunch that characterize Slash's sound. In addition, Seymour Duncan enhances the APH-2 pickups with some of the same appointments found on the Duncan pickups seen in Slash's '86 recording axe: a single-conductor cable, a long-legged bottom plate, and a wooden spacer. For true fans, or for players who want to capture Slash's recorded tone, these Seymour Duncan pickups are a critical part of the tone chain. These are same pickups found in the newest Gibson Slash model Les Paul guitar.Please message us if you have any questions.
