I have a Danelectro and Fender Jazzmaster that I just put into whack on accident by adjusting some things. On the Danelectro it starts to fret out at about the 10th and 11th fret on the E and A string.

As for my Jazzmaster I just replaced strings, staying true to the previous 10 gauge strings.
There is unbelievable buzzing, I don't want to adjust the bridge because It was never adjusted before and I'm afraid it wont play the same :'( It use to play great.

Any tips to bring these guitars out of whack?
