there's a 6 string at bass northwest for 2500. awesome bass, plays great...sounds like, well, an alembic. balances well, though it was a little heavy
I've had an Alembic Rogue 5 (Europa electronics and their first-ever one piece top, spalted english beech) for several months now. It's the first bass I've ever owned that teaches ME something new every time I play it, and I'm loving it. PRO - Balances very nicely on a strap, no neck dive. The sound is even, balanced, and articulate everywhere on the fast, flat neck. Sustain and fundamental out the ying-yang. Woodwork and fretwork is immaculate (no protruding frets so far). Studio-quiet electronics that offer great flexibility. A very easy, responsive bass to play. CON - A "middleweight" bass, not the lightest but not the heaviest I've played. Other than the weight, I can't find anything wrong with it. Can't help with the used price, but there seem to be some nice private-party deals these days.
obviously it's not related to the lowest of the low....(holy crap, that was a pun)... I actually like that shape the best out of all of their body shapes....too bad it has the same name as those pieces of poo that just barely pass off as basses..... A yin yang by any other name is still a yin yang; Call it a rogue, and you could get either yin or yang.
JR, I have this exact bass, NO complaints at all except it is on the heavy side, the used prices I have seen on these usually start AT LEAST close to 1500-2000, like I said, thats what I have seen, but you may luck up and get one cheaper.
