the body shapes, bracing patterns &, in some cases, body depth & scale length are different from
a nearly 20 year old guitar to a current model, or one made in that past 8 years in the X12s case -
the pre-00 X12 models, save for the 91 412 & 92 812 deep, had a body depth of 4 1/8", rather than
4 3/8" & the body contours more closely resembled an OM shape, rather than scaled down X14
a current model is unlikely to have tone that's directly comparable to one that's 20 years old,
whether or not the older one has a lot of playing time on it, provided it's been looked after -
there are other builders that try to recapture the tone of guitars made around 80 years ago &
even if the wood sets used were from the same era, it's not going to have "it" right out-of-the-box
but depending on how many or few, changes were made to that model of guitar, there may be less
of a perceivable difference than one that last year's model or perhaps even a few years old ... or not
