Petrucci Tuning...

Hey guys, is there a way to speed up the process of tuning stability on the Petrucci? The guitar tech guys said that it may take a few weeks for the springs to stabalise or something... Also.... on the bridge end, one of the little bits has sunk down, where the string goes into, it looks like its held up by screws, how can I get to it and fix it?

Hmmmm....What guitar tech guys are you talking about? EB customer service? I've never heard of this. My JP was rock solid when I got it. Are you sure they're not talking about the strings? It's always a good idea to stretch new strings a bit when you first put them on to help get them to a stable point quicker.

As far as 'the little bits', are you talking about the bridge saddles? The bridge saddle height can be adjusted by using a 1.5mm allen wrench. There are two screws - one on either side of the string. If this isn't what you are talking about, can you send a pic?

Unfortunately can't take good picture atm.... <a href="http://img95.imageshack.us/my.php?image=dsc00069uk.jpg" target="_blank"><img src="http://img95.imageshack.us/img95/1188/dsc00069uk.th.jpg" border="0" alt="Free Image Hosting at www.ImageShack.us" /></a>
on my guitar, which is 7 string, there are 7 of them..... its where the string goes in directly, one of them has collapsed on one side....
 
Ok - let's try this. Take a look at the pic below. Keep in mind I have the 6 string version with piezo. I'm hoping it will still be close...

"1" is the bridge saddle
"2" identifies the allen screws to adjust the height. Ideally, the saddle should be level. If it is collapsed on one side, then you should adjust the screw to bring up the collapsed side. Keep in mind that this will also raise the action on that string.

Does that help?

Its number 2, thanks for the help.... but unfrotunately.. I'm not sure what tools are needed for the small holes! You said allen key.. but thats for the large screws?

The bridge posts use a 4mm allen I believe. The small ones we are talking about should take a 1.5mm allen wrench. That's what mine take....

1.5 mm allen key? ok... there won't be any damage to the guitar whilst I find one, which may take a week due to time constraints! Suprisingly, neither mine or my dads tool boxes, contain a small allen key!....... Do you have any idea about the tremelo, and the possible reasons why it can't stay in tune?
Edit: I found something which worked as an allen key... thats fixed it! now to fix the tremelo!.. any ideas? I've heard something about graphite?

Well, yeah, if the problem is with the guitar going out of tune when you use the tremolo, one POSSIBLE reason could be friction in the nut slots. Some people find putting a little graphite there helps the strings slide over the nut more easily.

As OC asked, have you stretched your strings? Are they strung properly? With locking tuners, you don't need winds around the posts. If you put the strings on like a guitar without locking tuners (ie, winds around the tuning posts), it will also cause problems with tuning stability.

Just another thought.

I didn't wind them..... I will try the graphite thing.... will pencil lead do, or will I have to buy real graphite bits? I think I've stretched the strings, but how long and how much and how?
 
pencil lead is fine just run the tip up and down the slots like you are drawing a line in the slots. the strings should stretch after a good practice session

I can't offer any help with the graphite - I've never actually tried it. On the strings, just give them 3-5 good pulls. Obviously, don't pull them hard enough to break them. After stretching, I usually find that things settle down after a good practice session or so.

The nuts are near the headstock right? After graphite... if it doesn't work, what should I do?

If it doesn't work (and if nobody else responds with more ideas), I'd suggest calling customer service. I'm out...

Guys, I think I've found the problem...

does anyone know whether there are meant to groves there!.... not on the nut, but slightly above it! It looks like the strings have burrowed itself in... I've only just noticed when I slacked a string! Also I notice that guitar goes out of tune immediately even after tuning..... odd....., its ever so slight. but even my old guitar stays in tune!

I agree with Raz. It SHOULDN'T go out of tune each time you use the whammy.

From your pic though, I'd say you have a problem. That doesn't look normal at all. Time for a repair call...

how old is the guitar ? how much has it been played ? who's the tech you speak of ?
looks like the strings are not clearing the fingerboard & they are binding up on it....preventing it from returning to proper pitch. the nut is worn out...or someone tried to recarve the nut slots & boogered it up ) . i think you need a new nut cut.
