if one of the videos was shot in 97 & it's the same guitar in both, from the
body contours, relative to the pickguard, it would be either a 96 or 97 814c,
with the Fishman onboard pre-amp installed (or, it could be a 'proto 814ce)
in the amex video i can see the
progressive diamond fretmarkers & 3 ring ab rosette 0:11
fishman onboard pre-amp 3;39
gold Grover tuners 3:46
with the feedback buster in place, i can't verify if it is
a later 98 model (which had the label affixed to the back) &
his picking hand is covering the bridge so that the pinhole configuration
cannot be seen ('smiley' arc on 96-98 & possibly some 99 models)
