Ta and appreciated... the RD is flawed, but so am I...
I have two neck-thrus... that Thunderbird, which is a Peter Cook, and my "budget buy" in the 80's, a Hohner Jack... curiously enough, both have a an exact replica P "D" profile P neck, in four pieces: three for the neck, one for the board... both are mahogany or similar (in the latter case)... both play beautifully...
I'd love a fretless neck-thru, but the RD is a stunner for tone... all that maple... the original pups were active but were humbuckers with no electronics other than the Moog board...
I'd love to buy and convert an Epi Pro T'Bird to fretless at some point, but more pressing matters exist for me at the moment...
