Dwarfcraft Devices Necromancer Fuzz True bypass Powered by the industry standard 9v center negative power plug Enclosure Size = 4.67" x 3.68" x 1.18" While designed primarily for guitar, the Necromancer is happy to destroy anything you can stick in its jack, and does exemplary work with the electric bass. While rooted in the world of Old School Fuzz (and capable of many of those classic tones) there are also plenty of new and exciting textures in the Necromancer, thanks to its wide feature set, and slightly higher gain.
