I just picked up an LB76 on eBay. I never played a 6er before, and I'm having a wonderful time with it. The neck is quite comfortable. It has the single coil pickups, but is very quiet.
If I was buying one new, I would go for the long-scale option, the 35 incher. That would tighten up the B string a bit. But other than that, I'm happy with it.
I've played Soundgear basses before ... if you need speed, or play "lead bass", go for it. But I found the necks were too narrow and thin for me. Personal preference. Others just love the speed in which you can rip.
