When I mentioned that I made it the only 450B, I meant that I made it into an Octave Bass, 8-strings.
Kramer Guitars did not produce any 450B basses as an 8 string.
Only GHS majesty’s strings long enough for the Octave set; 38”
it leaves about 1” to wind onto the tuners
i put on a Badass. bridge and custom filed the nut and bridge tuners for Double strings.
Hello my name is Richard I own two Kramer bases
one is a Duke travel bass
the other is a 1979 450B
possibly the only one ever;
as I made it such years ago
it plays more like a piano
