same pickups (if your '94 has Lakland/Hansons), and probably same LH-3 preamp. If your '94 has Barts or other variant, then there's that difference.
differences will be in fit/finish, a semi gloss neck versus the wax/oil neck of the US, not sure about graphite in the neck for the 5-string Skyline (I seem to remember 5 string Skylines have the graphite rods, 4-strings do not).
But playability should be much the same, and I would recommend a 55-02 as a backup to any US 55-94.
Mine is a 1997. It came with the Bartolini Preamp and Pickup combination. I switched the pups several years ago to a Nordy MM and Seymour Duncan Basslines J for a more aggressive sound. The Barts, to my ears, were to well behaved.
What about the profile of the neck? The 55-94's neck is a perfect combination of flat radius and wideness. Very comfortable. What do the Hanson Pre and pups sound like? How do they compare with what I have?
