My MIM P doesn't "exactly" line up. The pickguard itself on the Schecter is even shaped a little differently. You could get it to work, but it wouldn't be perfect. I wonder if there's any where you can buy genuine Schecter parts?
You'd probably have to contact Schecter directly. Most likely they only have black and tortise -since those are the colors on the existing models- and that's assuming they're even willing to sell you one. When I contacted ESP about buying an extra for my LTD 214 they said they don't offer any except for warranty repairs.
Definitely worth a try though and there are also a few different companies that will make you a replacement in any style you want if you send them your original or a tracing.
