Wait a sec, the Petrucci bridge is like a Jackson? I thought the whole deal was "It's a floyd but it's not" so you could do Floyd tricks and not have the hassle of changing strings on them. I thought I could drop the 6th string for a drop tuning for whatever I was in as well easily and back up or tune it down a half step.
Is this not so? That totally changed my perspective. If it's going to be just like having a Floyd Rose, I'm going to get a JP7 or Universe for sure. If I don't have the freedom of a non-tremolo guitar then this kind of nullified my whole debate for the 6 or 7 string.
