Oh yes, very nice idea
I was a bit thrown by the staining at first, but I see what you are going for now!
Some pics of the two necks would be nice, but I like a chunky neck, the fatter profile, the better, so I would go for the Allparts and just the single Wizard (which I understand are very good). Traditional, I know, but everyone needs an old school P bass in the toybox.
Is that a gold anodised scratchplate as well?
Hope it is, I have a real hankering lately, to make a maple necked '57ish P bass with an anodised scratchplate, I'm thinking of a yellowed out LPB or maybe one of the old metallic greens.
Reading your thread will not be good for me!
