I might have a trade lined up for a "USA" bass but the big red flag of a rubbed off serial number is stopping me from trading. I found a thread on here from a google search that talked about stolen basses from way back having the serial number rubbed off. I'm looking for a keeper bass, so the missing serial isn't a deal breaker, but I'm hoping to find info from you guys here. Here's what I know: Transparent blue body White pickup covers 70's gold and black logo without patent info on the bottom. I found this site and it looks like the bass head that started in 1977. The potential trader bought it in 2004, so the logo predates the highway one switch to the same logo in 2006. The pickups could be aftermarket, but from digging around, it seems that white pickups aren't necessarily the most common thing. The pickups are yellowed a little, so who knows. Here are the two pictures I have so far and I've asked for more. I might stumble upon the info I'm looking for like I did with the recent MIJ model I asked about, but so far the same way I found info on that is turning up nada. Thanks for any help you might be able to give.
