Buying 2nd hand anything is a risk. Has a car been in a smash and put back together again? Does an amp have an electrical fault? Is a guitar pieced together from several? Well that was the claim about Eric Clapton’s Blackie, a Strat made from bits of Strats he liked. I don’t suppose that the fact that it’s a bitsa has affected the value of that one! 🎸
as has been said if it looks and plays ok and seems to be a reliable source then it probably is ok. If you buy with a credit card and it’s a rogue when you get it, you have some redress if the seller is reluctant to put matters right.
