Built for NAMM 2026 – Sold

Since the beginning, it has been a goal of ours to provide premium instruments for left-handed players. This Thunderhorse was the first-ever McGrath Guitars left-handed bass, built as a showpiece for NAMM 2026. Want one like it? Left-handed is an option on every bass in the Bass Builder.

Tone & Electronics

For this first lefty build, I wanted to keep the electronics classic and powerful. It features a versatile EMG trio paired with a high-headroom 18V system.

• Pickups: EMG TBHZ, Reverse PHZ, and JHZ configuration.

• Preamp: EMG BQ30 3-band EQ.

• Controls: Master Volume (Push/Push for Active/Passive bypass) and Switchcraft sliders for precise pickup selection.

• Power: 18V system powered by two 9V batteries, easily accessible from the back.

Premium Wood & Construction

• Body: One-piece Mahogany. I chose mahogany for its rich, warm resonance and incredible weight relief.

• Weight: An ultra-comfortable 7.4 lbs—perfect for long sets and studio sessions.

• Neck: Roasted Flame Maple neck and fretboard for superior stability and a smooth feel. 12" radius and 1.5" nut width.

• Frets: Durable Stainless Steel

• Stability: Dual carbon reinforcement rods with a two-way spoke nut truss rod.

Aesthetics & Hardware

• Finish: Our fan-favorite "Black Sands," hand-painted by Madelyn with a matching headstock.

• Pickguard: Simulated anodized black for a sleek, industrial look.
