Whenever hollowbodies are mentioned the feedback issue is immediately brought up but IMO it's not so bad at all. Also hollowbody There are also large differences between say a large body fully hollow jazz box / Casino, a thinline semisolid 335 (hollow wings but a solid core from the neck to the end pin) or a Tele with two added soundchambers and pretty thick top.
I'd be surprised if you ran into any feedback issues with thinline fenders. With 335's you'll pick up feedback (the nice harmonic kind) easier than with a solid but it's still controllable as long as you don't stand right next to a very loud amp. With my Casino things do get a bit hairy but that's a true hollowbody and I'd be dissapointed if it didn't go Neil Young on me from time to time :D The rawness is a big part of the appeal of that guitar. Still, with my well-potted BKP's no nasty squeling, just complex harmonic swells when you stop hitting it :twisted:
