I have mine paired with the Ampeg PF-50T Portaflex - 50W All-tube Bass Head. It is a match made in heaven. I've been using a Martin acoustic bass and can get tones from "very acoustic" to "total electric bass" and everything in between.
Then tweeter horn switch is a nice feature as one can attenuate, or eliminate completely all articulations and like textures at will. One can also get quite a thunderous output with just the 50 watts delivered by the tube amp. It is suitable for medium sized venues on down to the studio recording. When done, everything, including the amp, fits in the cabinet which has detachable casters to wheel it out to your car. And if you want to play a bigger room, the cab is rated up to 450 watts with which would able to generate "ear wax melting" bass.
I Love Ampeg!
