Bassworks' Custom J5 series of basses owe some of their inspiration to the bold assymetric design leap made by Leo Fender in the 1950s with his dual pickup equipped basses and their slim comfortable neck profiles.


This one has a book-matched Franquette Walnut drop-top on a one-piece Swamp Ash body core, with a Wenge contrast laminate. It sports a pair of "boutique" Aero Instrument dual-coil pickups in matching wooden covers, from Larry Pollack out of Hawaii.


Despite their design influences, our instruments strive to improve on what has gone before. The Custom 5's chambered body being notably more compact and lightweight. Our 30+ years of playing and our skilled manufacture bring the tone, playability and reliability that bass players deserve to enjoy in the Custom 5 series. Crafted in small batches entirely in our own shop, every Custom 5 is built with the same painstaking attention to detail, using stable tone-woods and world-class electronics and hardware.
