I have no idea what they would be like with a Fender, but no reason to think it would be bad. I've had them through a JTM45 before and they still sounded good which I believe is a little Princeton-ish from what I vaguely recall reading somewhere. Between these, the Whole Lotta humbuckers and the DiMarzio PAF 36th, they were still my favorite set.I've played these before through a Marshall 1974x and they sounded awesome. I don't however own that amp and not sure how they would sound through my Princetons. It would seem those PU's have been specifically designed to play nice with Marshalls.
