Jackson Electric Guitar
One word of advice: If you are going to buy a San Dimas Charvel or Jackson, do your homework. The strat headstock Charvel is one of the most forged guitars of all time. It's also one of the most likely to have been messed with / modified. Finding a legitimate unmodified guitar with a neckplate that matches the logbook is truly rare. Also, with so little information available on these guitars, many end up being innocently (or otherwise) misrepresented. I would highly advise against buying a bolt-on San Dimas guitar without first verifying the serial number with the Jackson Custom Shop. This can be done on the Jacksonguitars.com website under the "Serial Number History Chart" link.
That being said, here is some information to help identify / authenticate San Dimas Charvels and Jacksons Guitars.
