I've just bought a Left-handed Precision bass kit. I've been knocked around by two severe doses of Flu so I haven't been able to do much more than check that all the bits are there! Looking forward to feeling well enough to start the actual assembly.
About 30 years ago I made a bass out of a 6-string guitar I bought for $12 in a second hand shop. It actually worked a lot better than it had any right to, but I always wanted to get a "proper" bass. However left-handed ones are difficult to come by, at least a a price I could justify.
