Here is what the Mark Stow, the creator of OX4 pickups, has to say about the Slash set:When Appetite for Destruction came out I was blown away by the sound and the playing. This is my interpretation of his tone. After trying a few different winds I have settled with a medium output and A5 magnets, plenty to top end bite and chunky rhythm tones.Each OX4 pickup is hand wound and assembled using the best materials and components available. Bobbins, baseplates, covers, slugs and keepers are made by Ox4 Pickups with vintage correct materials.
