Here are a few brands that currently offer 12-string basses
The Dean Rhapsody 12-string bass has been relatively unchanged for nearly two decades. Over this entire time you could always buy one in any finish or color that you wanted - as long as that color was transparent black. A few aftermarket custom-finished 12’s exist, but mostly, they all look alike.
Musicvox gets rave review in the music industry press for their retro styles and consistently great quality. Plus they have created some of the coolest vintage-style bass advertisements ever done!
Waterstone one-upped all other builders by signing up Cheap Trick’s Tom Petersson with the first-ever 12-string bass signature model. Waterstone 12’s come in a great assortment of finish colors.
