First thing that comes to mind is to contact Parkway Music (since they touched it last, supposedly) and ask them about it. You could also run the serial number thru the interwebzez and see if it even comes close to what they say it is.
yeah, I never thought to contact Parkway, I know those guys, I'm guessing they are going to say it's "all that" though. Hopefully, they'll give me the straight scoop.
Is there a specific website to check serial numbers, not familiar with doing that?
