Dude first off congrats for make what I consider the best decision any man can make. Not only are you buying what I consider to be the best guitar (well if it was a seven it would be the best so second best :tongue: ) but you are also going to be part of a family that takes care of their customers. You are set for life. I've bought many used EBMM guitars and any parts I needed, I simply called customer service and, bang there it was in the mail free. Make sure you join the forums over there as well

as they will be friendly and very helpful should you need it.
Now onto the guitar. Forget everything you know about the Floyd, the Petrucci is way better. I have an EBMM JP7 and a Wayne Custome 7 string, hand made by Wayne Charvel, while I love both guitars, comparing the trems is like comparing night and day. I will never buy another Floyd equipped guitar again. Changing strings, intonating and tuning on a FLoyd is a pain in the butt, however on the Petrucci, it's like making love on a beech, with the waves brushing up against you...HEAVEN. Changeing strings with the locking tuners takes about a couple of minutes, and once those strings are stretched, and the tuners locked, that guitar will hold its tune, even during massive whammy bar acrobatics. Now let's say you want to intonate this baby, simply turn the set screw, there's no special tools required and no need to loosen the string, like on the Floyd. Again should you need to set the guitar up, well the Petrucci trem can be set to follow the exact radius of the fretboard,do to its individual saddle heoght adjustments, unlike MOST Floyds which have to lay flat. Finally, should the neck require some fine tuning, the EBMMs come with a unique feature that no other guitar has, the truss wheel adjustment at the base of the neck, which is easy to turn and requires no special tool, no plate removal nor neck removal.
Hey ask yourself, what other company has the owner posting on the forums asking members for input, plus showing prototypes to the members...I can go on and on.
Here is a video of demonstrating its tuning stability:

Look how compact it is:
