Bass of the Week: John Sullivan 5-String Custom
We previously featured a bass by John Sullivan, who built his own bass to be a versatile workhorse. Now he’s shared a killer five-string.








The bolt-on design is crafted with a roasted swamp ash body, splayed maple top, and a neck of wenge, maple, and padauk. Sullivan reinforced the neck with graphite rods before fitting it with a Madagascar ebony fretboard finished with a compound radius.
For electronics, the bass has a pair of Delano Xtenders and a Sonar 3 preamp. Finally, Hipshot hardware ties it all together.
