A friend has one and I think they are a great sounding solution. Where is the forum?Nothing short of a doghouse is going to have enough umph to keep up with a band acoustically. But that said, there's some really nice amplified options out there.
You gotta check a Ubass. A good friend and x bandmate who'd always played doghouse showed up a couple of years ago with a Ubass at the big 48hr jam in Bakersfield. I can't remember what the amp is, but it's really small and the sound is absolutely great! It's just funny to see this big ol guy with an itty bitty uke looking thing, and then when you realize it's a bass, all most people could do was just marvel. I would have thought it wouldn't have much range but my buddy doesn't have any problem at all, any key, and somehow doesn't seem to run out of fretboard. He says he has no calluses, no hurtin' fingers, and best of all no more back problems from hauling that big ol' bass around. And somehow the Bluegrass Police haven't got riled up about it.
Just did a marathon crafts faire with a friend who's got a standup electric. Everybody in the audience, including several bass players raved about the sound. He brought the electric because he was camping in his small SUV and didn't have room for the doghouse. For me it was a snap to just come out of the pre out, straight into my board. No muss no fuss and sounded tremendous. Since we were doing a trio, I felt I needed to get his bass pretty loud and it was no problem at all. He was telling me it is fairly cheap($600) and there's forum's devoted to the tweeks that need to be done to make it work great. He also has a little battery powered bass amp so he can go to jams. Unfortunately he didn't mention the make and it had nothing on the bass anywhere as to maker that I could see. Just looked like standup neck with a very emaciated body. Pretty light and no bulk to speak of.
As with any amplified bass, you have be aware of your technique. The tendency is to have too much sustain so you loose the precision of the beat. So you have learn to mute.
