Because the seller wasn't up-front about this very important detail in his listing, I would have major reservations about buying from him.
Yeah, it did take me to make contact to find out that information.
But I've experienced this in many transactions.
It's always great to ask, but sometimes people forget these details.
And they're definitely important.
That fretted neck certainly looks like a half decent copy and to someone that doesn't know Wal that well, they probably wouldn't be happy if they found out after they already owned it.
Leaving any neck sitting around with no tension is not the best thing either.
I wonder if the truss rod works on the fretless neck?
Heck, leaving a bass with the strings on and not playing it for decades is bad enough.
So, who knows what could happen with this bass, it could be great too.
And being a 1986 with the two pots instead of the four pots, well, for a 5er, more pots are better for the low end control. For fretless, maybe not so much as the mids will probably be abundant enough in that bass.
I guess this bass is going to have the smaller pick-ups too like my 1987 MK2 5 fretless conversion and 1988 MK2
Polyester Black Wals had. They were fun basses!
