they should have a "110" after the "66B" in the code, if they have f-keys. as far as i can see, you actually pay quite a bit more for block inlay sunburst jaguars that have f-keys. whereas a block inlay sunburst jag with ping klusons cost quite a bit less (even though the only difference is the tuners. ie, the price difference is more than you would pay for a set of tuners). but i think that most of the custom colour block and binding japanese jaguars have them anyway. i could be wrong, but that's how it was on the ikeba or ishibash site last time i looked.
to be a faithful '66 reissue, it should have f-keys really
