McGrath Thunderhorse IV - Whiskey - 8.5 lbs

This Thunderhorse IV was engineered for players who love the punch of a triple "P" style configuration but crave a cleaner, more sophisticated aesthetic. Finished in a hand-painted Whiskey finish with a classic tortoise shell pickguard and nickel hardware, this bass strikes a perfect balance between vintage class and modern versatility.
