It started with the old P-bass - that seemed like a no-brainer. Then the fretless. Again, pretty obvious choice. For 8 years, it was contained to these two axes. Then I got a '51 reissue. Going to keep rounds on that? I don't think so... While I'm at it (placing a string order), might as well go ahead and flat out the old short-scale Musicmaster. I just got more flats in a trade, so I threw some on the Jazz bass, too. And I'm loving it - it's exactly what that axe has been needing. Suddenly I realize all I got left with round wounds is the active 5-string and the backup Steinberger (which I've always kind of wanted to change over). So my question is: is there a way to vaccinate these two against the flatworm? Or should I just cave in and do 'em all?
