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.

NS Design NXT Omni Bass

omni bass

From the sales brochure:
The NXT Series Omni Bass, with the familiar 34 inch bass guitar scale, is designed for the bass guitarist interested in adding the character and expressiveness of an upright bass to his performance palette.

The solid maple body and neck, together with the graduated fingerboard, deliver a rich, full tone that rings true for every note. The
adjustable bridge and truss rod allow for low, fast action, or for higher string settings that encourage the traditional acoustic player to ‘dig in’ with gusto. NS Electric Omni Bass Strings and standard bass guitar strings fit the Omni Bass, adding unlimited set up options for musicians who want to explore & create their own unique sound.


The self-powered Polar directional piezo pickup system, with high impedance output,
responds selectively to lateral string vibration, for bowing and for the percussive plucked
response of a traditional acoustic instrument, or to vertical string vibration, for remarkable
even and sustained plucked sound more like a guitar. A switch allows the player to choose the
desired response.


Self-powered piezo circuit with high impedance output, no batteries required. The Volume
control and Tone control (treble roll off) circuitry incorporate the JackPot, a circuit by which
the Volume control disengages the ground when turned fully clockwise, sending 100% of
the instrument’s signal to the amplifier.

The bass comes with softshell case, tripod stand, boomerang strap (to wear like an electric bass), and a bow. I bought this barely used and have barely used it since.
