Thunderhorse - 12 Way and Tilt EQ - White Sands

This is our flagship Thunderhorse, featuring our new 12-way pickup selector and McGrath Tilt EQ. Finished in a striking White Sands, this instrument is a refined evolution of our signature P-Style design. The body and headstock are uniquely hand-painted by Madelyn McGrath, making this bass a true work of art.

Pickups: Equipped with three EMG HZ passive pickups configured in our signature layout: Thunderbird, Reverse P, and J.

12-Way Rotary Selector: Delivers massive tonal versatility across 12 distinct pickup settings:

All 3 Parallel

Bridge Only

Middle Only

Neck Only

Bridge & Middle Parallel

Middle & Neck Parallel

Bridge & Neck Parallel

Bridge & Middle Series

Middle & Neck Series

Bridge & Neck Series

Neck & Middle Series + Bridge Parallel

All Three Series

Push-Button Functions:

Save: Long-press to save your current setting.

Recall: Push to jump to your saved favorite; push again to return to your previous setting.

Reset: Triple-tap to return to Position 1.

Failsafe: Defaults to Position 1 (All 3 Parallel) if power is lost.

McGrath Tilt EQ: A single-pot active preamp and buffer. Turning the center-detented knob yields glassy highs in one direction and rich, powerful low end in the other. Includes a passive tone control for ultimate versatility.

18V Active System & Passive Bypass: Easily bypass the active preamp using the push-pull Master Volume knob. If battery power drops during a set, pulling the volume knob defaults the circuit to running all three pickups in passive parallel mode.
