It sure is a generalization but every time i picked up a (fender) custom shop guitar I was unimpressed. Besides obvious problems like rattling saddles, badly adjusted necks etc. (which shouldn't happen on 3 k guitars IMHO) I never thought that they sound or play superior to the production guitars I have. In my town there is a big store with a huge selection in their "custom shop room" and I go there from time to time just to see if I find something special. I never did so far. The relic finishes may be a reason to get into them for some but personally I find them rather exaggerated.
