This gets asked a lot for some reason. The answer is no. You will have to retune the entire guitar if you change the pitch of one string. The reason is the JP has a floating tremolo. The tremolo bridge requires a delicate balance of tension between the strings and the springs in the back. If you change the tension of one of the strings (by changing the pitch), you'll have to find a new "balance" for all the strings by retuning again.

Practically speaking, if you tuned the E to a D, then all the other strings will go sharp. Then you'll have to retune all of them, and when you do, your tremolo bridge will be sitting a bit lower inside the cavity than before because of the lower tension.

Because the bridge will re-adjust when you retune all the strings, you may experience different action than before (with notes cutting off a possibility) and you may need further set-up adjustments.

thanks.. i'll just have to get another ball.. :p and the morpheus droptune..

Both good options.

This is why John Petrucci (and other floating trem players) carry around so many identical guitars on tour. They are all tuned differently, therefore requiring completely different setups and sometimes even different string gauges.

Ideally, we'd all be able to afford that may guitars. :)

Did you mean drop it on the "fly"; like with a D-Tuna in the middle of a song??

Yes, you can, however the guitar needs to be set up correctly and be tight, with no other issues. There are also things you can do to re-inforce tuning stability; just check around different sites.

get a tremel-no. it locks the bridge into dive only postition or you can lock it out effectively turning it into a hardtail. i am in the exact same situation as you with my JP's and i have a tremelno on order.

Dumb question from me.....you can put a D-Tuna on a Pet? I don't think so....again...I could be wrong but have never seen it. I only thought they worked on Floyd Trems....

kdj771 made a good suggestion as well.

The better one is to buy another guitar....lol....;)

Can't put a D-tuna on a JP.

Best bet is a Tremol-no. Works great. You can instal one in 20 minutes yourself. Easy.

+1.
I have it installed in my cherryburst and it works like a charm. Plus with the morpheus, you can tune down to the depths of hell. :D

Lou is right. The D-Tuna replaces one of the Floyd saddle screws - which are completely different from the JP trem. I had one for a while on another guitar and could never get it fine-tuned just right - so I ended up selling it.

Incidentally, the OP question is the reason the D-Tuna specifies that you need to block the trem before installation - to avoid the other strings from going sharp when you drop to D.

The clamp type is the old style. I have one and it requires a trem block 'adaptor' because the JP Block is not flat, it's angled. Pin type will work for you.
