Ah, I just saw you were the builder of those nice basses you posted the picture of. I can understand the frustration of someone coming up with their own 'somewhat different than J Bass' designs, with the fancy wood tops and everything, and then see a lot of us gushing over Sadowsky and Alleva and Lull, etc. basses.
Having gone through a VERY expensive and long 'hippie sandwich/coffee table' stage (my MTD/Fodera/Smith/FBass era

), I can appreciate the wood work and the beauty of some of these designs (including yours!). However, I've never found all that to improve the tone or playability of the more classic designs (P or J)... just 'change it' a bit. Depending on the players preference, that 'change' can be to the positive or negative. IMO.
