i had a 06 DN Proto that had the aesthetics of a DN5 (with scarfjoint headstock) &
the 'guts' of a RTS3 (body shape/taper, solid lining & sides braces) ...
to my ear, the tone was 'lacking', but i like the DN too - the older sitka/rosewood
models really 'have it', imho, & there's an especially nice 410MA that recently
joined the stable & it will likely be my 'bench-mark' for a large body maple
