Would anyone happen to know the best possible replacement for the middle pickup on my '89 UCMD RG? The guy I bought it from not only mashed her up quite well, but he removed the stock center pickup and I was wondering if anyone has any information about getting it replaced? All I found so far is...

I'm selling this Ibanez USA Custom. I believe it's the UCMD1GS 'Gray Snake', though correct me if I'm wrong on the exact designation. Serial number is from 1989. I bought this from a guitar shop and they set it up and intonated it for me just about a week or two ago. It plays and sounds perfect...
