Thanks for the input rosskratter. However, those Hartke cabs look way to heavy for what I had in mind. I'm looking for a quality lightweight rig that can handle the bass sound reinforcement job for my upright and will let the warm tones and thump of aged-wood and long strings to support, and cut through when needed, an amplified mix of voices, guitars, mandolin, fiddle, percussion, and banjo for my Bluegrass/Americana gigs.
I was looking for specific feed back on the EA doubler and Wizzy 10 for Double Bass, after this long thread of options, I was curious if the originator was satisfied with the final decision.
