McGrath Thumper - J-Style 2026 - White Sands

McGrath J-Style White Sands Thumper

If you are looking for a shortscale powerhouse, this is it. This J-Style features a solid Hard Ash body finished in our striking White Sands aesthetic. Every McGrath build is a unique, one-of-one creation—a functional art piece designed to be as visually commanding as it is sonically dominant.

The Thumper Heart

This instrument is built around the Thumper configuration, utilizing a high-output pairing of passive EMG TBHZ and reversed PHZ pickups. To optimize playability, we moved the neck pickup back 3/8", creating a dedicated landing zone for slap players without sacrificing that signature deep-position low end.

Performance & Ergonomics

The J-Style represents a player-first evolution in the McGrath range. It features deep, ergonomic contours and a perfectly balanced profile designed to eliminate neck dive. The sculpted heel provides effortless access to the higher register, ensuring the full 30" scale is always at your fingertips.

Handcrafted in San Diego

The bass shown in these photos is the exact instrument you will receive. McGrath is a two-person team based in San Diego, California, and we put our heart and soul into every one-off build.
