The Ultimate Lefty Bass: Introducing the McGrath Thunderhorse 'Black Sands

For years, left-handed players have had to settle for limited options when it comes to premium instruments. At McGrath Guitars, we’ve made it our mission to change that. We are proud to unveil our first-ever left-handed bass: the Thunderhorse IV in "Black Sands," specifically built as a showpiece for NAMM 2026.

Crafted for the Stage and Studio

This isn't just a mirrored version of a righty bass; it is a world-class instrument designed for modern performance and classic feel. Weighing in at an ultra-comfortable 7.4 lbs, the one-piece Mahogany body offers rich resonance without the back strain during long sets.

Premium Specs at a Glance

• Unique Aesthetic: Features a hand-painted "Black Sands" finish by Madelyn with a matching headstock and a sleek, simulated anodized black pickguard.

• The Neck: A Roasted Flame Maple neck and fretboard provide superior stability and a smooth, lightning-fast feel.

• Bulletproof Hardware: Outfitted with high-durability stainless steel frets, a high-mass Badass bridge, and nickel tuners.

• Reliable Stability: Dual carbon reinforcement rods ensure the neck stays true regardless of the environment.

Classic Tone, Modern Power

To ensure this first lefty build packed a punch, we went with a versatile EMG trio (TBHZ, Reverse PHZ, and JHZ) paired with a high-headroom 18V system. Whether you need precise pickup selection via Switchcraft sliders or the ability to bypass the active preamp for a passive vibe, the Thunderhorse delivers.

This specific model was built to showcase the best of what we do at the world's biggest gear show. While this "Black Sands" beauty is a rare opportunity, it represents the new standard for our left-handed offerings moving forward.
