Check PRS Warranty - Electrics are warrantied for 2yrs which is very reasonable - from new assuming you are using 'everything' as it was intended and not changed things. PRS can only guarantee that it left the Factory 'perfect' and had been checked thoroughly by the person on the hangtag. After that it was double checked and packed away. What happens after that is the 'responsibility' of the dealer who sold the instrument as they 'received' perfect instruments. If 'parts' fail, which they generally do quite early if faulty, are covered by Warranty.
As far as PRS are concerned, they sold a 'perfect' and thoroughly well checked Instrument to their dealer. That retailer then sells the instrument to you and if you have a 'faulty' part, you go back to the retailer who fixes it with a straight replacement from PRS if its within the warranty and its not a 'user' created issue. You know the date that guitar was Checked, that was about the last time PRS saw your guitar and it was working then - a lot can happen in the time between them saying your guitar was worthy to be released and you getting your hands on it - how many different people could of messed with 'something' - especially in some shops where all their guitars are out for anyone to 'try'...
If you are buying used, regardless of whether its listed as 'mint' or not, any issues are with the previous owner who either hasn't been strictly 'honest' or was in a rush to put the stock pups back in...
Things can be faulty and fail after a short time, that's why you have warranties and whilst every company may strive to put out 100% perfect product 100% of the time with zero 'faulty' parts that never fail, that is an impossibility. So what sets Companies apart in my opinion is what they do to fix issues, fix faulty parts etc - not fix other users mistakes/accidents - and PRS have an excellent reputation there. So if you buy 'new', you have excellent warranty and support, buying used can be 'hit' and 'miss' because you are 'trusting' the previous owner who is trying to get as much money back as they can, may not even be the OG owner either....
