Hello out there PRS owners. I am new to the forum but have owned one since 1990. My '89 Signature has a sweet switch and a tone pot and I've never seen another with both those controls. I bought it new and am sure it came from the factory that way. The factory hang tag says "Special Package." I have been wondering if it is a "one off." I tried to find out from PRS and they didn't have good records of the guitars they made back then, but no one could remember having made or shipped out one with both features. So I'm reaching out to forum users to see if anyone knows of another in existence. I look forward to corresponding with you.
