The Alnico 2 Classic is a superb humbucker set for guitars that need more warmth, fullness and sustain. At higher gain settings, the Alnico II Classic really nails the fluid distortion sound of players like Slash, who use the smooth attack and longer sustain of the neck to great effect during solos, and the tighter, fizzier tones available from the bridge for rock rhythm work. All AC2 pickups are fully wax potted to avoid microphonic feedback, and come with supplied with #3/48 screws, springs and an installation guide. Available individually or as a set. Four conductor wiring as standard on all models. Neck 7.5k / Bridge 8.3k / F-spaced Bridge 8.5k, Alnico 2
