I've had an old Rockbass Streamer, the one with the precision style bridge and two soapbar pickups. If the one you've seen is the same, the neck is very slim, jazz-ish. They are quite heavy though, but comfortable to play. I had mine modded before I got it with an MEC active circuit, so couldn't tell what it sounded like before, but the active sound was great.... Good value as well.
