So I just got a used 7-string w/ a Floyd Rose (Schecter Jeff Loomis Signature). It had some really heavy gauge strings on it, and was tuned down quite a bit. I replaced them with some 10s (10-56) and tuned to standard B-E-A-D-G-B-E. Unfortunately, the strings keep going sharp by almost a whole step, even though I changed them last night.

I was wondering if this is a sign of spring and string tensions being unequal, but the bridge seems pretty level. Adjusting a FR is pretty new to me so if you have any ideas what might be going on, I'd really appreciate your input. Thanks.
