Ampeg AMUB-1 fretless 4-string electric bass

Ampeg AMUB-1 fretless 4-string electric bass. Called the “Scroll Bass”. AMUB-1 stands for Ampeg Magnetic Unfretted Bass series 1.


Ampeg built about 200 AMUB-1 basses during the late 1960s. 000210 represents the serial number of this instrument.

Rick Danko of the group The Band played the same model of bass.

Bruce Johnson at told me that Ampeg likely made the bass pictured here for a Trade Show exhibit or as a Presentation Model for an executive. He NEVER before saw this model of the bass in the color white.

I touched this bass for the first time 40 years ago. The Ampeg stayed in the case for many years before I recently purchased the instrument. The seller did not play the bass.
