Specs: Winter-summer of 1964, no changes. Fall of 1964: Headstock logo decal changes to "transition" logo - thicker gold script and four patent numbers: 2,573,254, 2,741,146, 2,960,900, and 3,143,028, pearl fingerboard dots replace clay, mint green pickguard replaced by white pickguard on some late 1964s, the name "Kluson Deluxe" on the tuners now takes up two lines as opposed to the previous "single line" name stamp, pickup bottoms are gray instead of black, and the metal spacer below the string tree becomes white plastic.
Notes: When the transition specs appear the sunburst takes on a slightly different look, especially noticeable in the yellow.
