Thought I'd post this cool mod that I found on eBay 
Vintage Pre Ernie Ball Fretless Stingray Bass (eBay item 190502994710 end time 24-Feb-11 14:22:49 AEDST) : Musical Instruments




What makes this even rarer is that it appears to have had 2 frets installed in the upper register at the factory. The job is so good this is the only way in my mind it could have been done. This way you get fretless however on the two lower strings you can slap. This is as good as it gets.
