I have a Charvel electric guitar, that i assume is Model 5, but previous owner replace the jt6 tremolo with some cheap licensed floyd. everything else on a guitar, pickups, tuners is made by jackson. the serial number is C 803826 and is written on the last fret of the guitar. can i identify that serial number on the internet and how? i never do this before.. i am asking myself if the guitar is too old to even identify on the net?
