Quote - IIRC, the first ever was the Telecaster styled Precision...

You remember correctly, to the best of my knowledge. Mask-Da had a model of the Telecaster bass, which was the reissued version of the original precision, but it's been rotated out of his site at the moment.

Quote - No reason not to boast about having a 6 string bass

I guess you haven't seen the Bassist Infraction Notification Form. I owe quite a tidy sum, according to that. :)

Mine's a Shergold Marathon (like the picture, but minus the stripes). I can play it, but for most things I prefer my home-built Fender Jazz copy. Having extra strings is too tempting and tends to attract more fines. :)
