P-Style Thunderhorse 4 - Celestial Blue - 8.6 lbs

McGrath Thunderhorse IV –  Celestial Blue 

This Thunderhorse IV is finished in Celestial Blue, a rare finish we’ve only produced once before. To improve playability for slap style, we’ve updated the neck pickup position, moving it back 3/8 inch to provide extra clearance.

The body and headstock are hand-painted by Madelyn McGrath, making this instrument a unique, one-of-a-kind work of art.
