The S-607 brings the S-600 platform into the realm of seven-string guitars. Built around a new, lightweight swamp ash body with an ergonomic shape and a 26.5-inch scale, it keeps the low B tight, focused, and melodic, while maintaining the fast and stable feel of Spira’s modern S-type platform.

The roasted maple neck and fingerboard ensure immediate and stable response across the instrument's entire range. The twenty-four stainless steel frets are an upgrade that is immediately noticeable. Softer to the touch, more durable than typical nickel, and more precise across the length of the fingerboard, they give the S-607 an elegant high-end feel.

The Spira Villain humbuckers deliver the high-performance sound characteristic of Spira: tight lows, clear highs, and enough power for modern rock and metal without loss of clarity. Enhanced by Spira’s new high-mass hardtail bridge, with individually adjustable saddles for precise tuning and strong sustain, as well as locking tuners for stability.

The open-grain finishes highlight the wood rather than conceal it. Since the wood grain is never the same, each S-607 has its own unique appearance.
