Bill Kelliher engineered Mastodon’s heaviest riffs on a platform that doesn’t fit traditional guitar categories. The ESP LTD Royal Shiva is a double-cutaway neck-through design that blends accessibility with raw tonal power—a guitar built for complex rhythmic ideas and sustained aggression.
The body shape is proprietary—wider than a typical SG, with deeper horns and a more aggressive cutaway angle. Mahogany construction, neck-through for maximum sustain, finished in a dark stain that reveals grain detail. Pick it up and you feel the intentional weight distribution—it sits naturally on your leg and balances during standing performances without requiring a strap lock.

The neck is a modern fast profile, with a subtle V-shape that encourages thumb-over technique for palm-muting. Twenty-four jumbo frets, sharp crowns, zero dead zones even at the 23rd fret. The rosewood is dark and tight-grained, with a natural matte finish.
Fishman Fluence Modern pickups are dual-voicing stainless steel rails—push-pull pot switches between classic and modern output levels. The bridge position cuts through a dense mix with aggressive presence, while the neck maintains focus in palm-muted chugging. These pickups excel at tracking fast alternate picking and complex polyrhythmic patterns without lag or artifact noise.

vs. PRS Custom 24 in Black Limba: PRS offers more refined craftsmanship but less aggressive aesthetics. The Shiva is built for metal, not all-genre versatility.
