The S-600 is the S-Series taken to a higher level. Built around a new, lightweight swamp ash body with an ergonomic shape, it offers faster response, clearer note articulation, and a more luxurious feel when playing on Spira's modern S-type platform. The roasted maple neck and fingerboard ensure speed, stability, and immediate readiness to play from the very first note. The twenty-four stainless steel frets are an upgrade that is immediately noticeable. Softer on the fingers, more durable than typical nickel, and more precise across the entire fingerboard length, they give the S-600 the elegant high-end feel usually found in models at much higher price points. The Spira Villain humbuckers deliver high-performance sound with tight bass, clear trebles, and enough power for modern rock and metal without losing clarity. Enhanced by Spira’s new large-mass hardtail bridge, with individually adjustable saddles for precise tuning and strong sustain, as well as locking-type tuning machines for stability. The open-grain finishes highlight the wood rather than conceal it, resulting in each S-600 having its own unique appearance.
