I need to intonate my strat but I'm having a bit of trouble.

I'm loosening the saddle screw to flatten the pitch and retuning, but I just get the same wrong pitch! I am willing to bet that it is because of the tremelo. Should I block it off, then tune and intonate, unblock, then retune?

As a side, what do you guys think of signing the salesmen that spam up UG for porn? Obviously, we could only do this to ones that leave an email address, but I want Vengeance!

Thanks guys!
