The BTB575FM 5-string bass guitar has the kind of curves that would make Boticelli proud. An apple bottom with a long, thin upper horn and deep cutaways on both sides of the fret, it's an electric bass that will stand out in any situation on visuals alone. Where the fretboard and body meet, the BTB575FM's finish is angled downward crossways adding to its allure. The 5-piece maple/bubinga thru-neck and figured maple top complete with the optical stimulus. Soundwise, the mahogany body gives off plenty of smooth tones given some oomph by the dual MK2-5 pickups.
