Once this gets officially marked as lost, I won't try barking up a similar tree - I figured that kind of money was pseudo-worth-it if I got exactly what I wanted, and the SB-1 would have been that.
If fate decides I'm not getting exactly what I want, rather than get second best, I'll just aim lower and in a different direction and perhaps push my boundaries a bit eg fit a dimarzio P to a used MIJ Precision, risk trying a bigger neck.
When the SB-1 was returned to the factory in December and I knew I had a fair bit more waiting to do, at least, I bought a BB424 which I've been extremely happy with. Perhaps instead of having one perfect bass plus a backup I'll have two or three middling basses that make me equally happy in different ways. One can tire out my left hand, one can tire out my shoulders, one can sit there looking pretty ... or handsomely knackered ....
The thing about dreaming up plans is that you never know if they're actually right for you until the opportunity comes to put them into action. Since that moment isn't imminent, I might as well equip myself with a whole bunch of them
