Kiesel Allan Holdsworth Model Pickup Set Neck 6.9 Bridge 8.8 Alnico 5, PAF-style, well-balanced. The neck pickup isn't dark and can be used with tapping. The Holdsworth bridge pickup, co-designed by Allan Holdsworth and Mark Kiesel, is tuned to perfectly capture Holdsworth's fluid playing style. Unlike other Kiesel pickups, this pickup is not wax potted, which brings further clarity and sustain to Allan Holdsworth's playing. Like the Holdsworth bridge pickup, the Holdsworth neck pickup is also not wax potted, making it ideal for jazz/fusion neck pickup tones and an excellent match for the Holdsworth bridge pickup.
