I scored a squabin 5909 bridge off of ebay and decided to put it in my McCarty today. So far I would say it sounds really good but with me, I could play it at home all day long and never know for sure until gig time. Any changes to my rig or guitars can't be judged until I gig with it.
The squabin looks good in there and sounds even better so I may just look for a squabin 5909 neck and put it in too. Gotta gig first though!
