Love that neck through sound. But I love that set neck punchiness. So why not have both?
I'm thinking take the neck through design but halve the neck wood volume as it gets to the body. Maybe that will increase the punchiness without sacrificing too much of that tone.
So I'm thinking a short scale series II (starting off expensive here, but for a dream bass, why not?). Body in-between a balanced k and the essence. Neck lams: gotta have ebony + purple heart combo with maple. Maybe some mahogany. Side LEDs in blue, of course.
The body: how about 9 layers? 5A buckey burl (or coco), maple, ebony (or purple heart), maple, myrtle (or walnut), maple, ebony (or purple heart), maple, 5A buckeye burl. Top and bottom two or three layers bookmatched to center.
Top it off with wood pickup covers.
Beautiful as hell, but how will it play? Wont know until it's built!
Definitely a 20k+ bass.
A more budget solution I guess would be just take the Stanley Clark deluxe and do the neck/bookmatched thing.
