Kodiakblair - I've got one exactly like that, the white fretless with the extended fretboard and piezos. I bought it new in 1986 - as soon as I heard about it it sounded like just what I needed. I've loved it ever since! I've used it a lot for jazz and soul, through a Polytone MB II - the combination of the piezo and being fretless give it a lovely woody tone. It's currently got black tapewound La Bella strings on it - I suspect that's what it came with in the first place. It really sings.
I don't really play any more though - would you be looking for one? I'm in Edinburgh if you wanted to pop over for a play.
