rg prestige 2550z doesn't stay in tune

Hi

I have a slight issue with my 2550z. The guitar is equipped with the edge zero tremolo with the zps removed (I didn't like the feel of the floyd with it on).

The problem is that when I lower the bar, all the strings go a little flat. When I pull up on it, they all go a little sharp. I don't have to move it a whole lot for this to happen (let's say i'm changing the tone by less than a full tone when using the bar).

The floyd is setup paralel to the guitar, so this shouldn't be an issue. Any ideas?

Thanks!

yeah, i'm sure that's why it's not staying in tune...

also, are the strings really stretched in?

If the strings arn't totally stretched you will never get a floating trem to stay in tune.

Re: rg prestige 2550z doesn't stay in tune

I haven't adjusted the edge zero tremolo but any trem would need the advice on setting up found on this site...

It includes: -
1. Tighten the screws holding the locking nut (not over-forced) - they are slightly loose from the factory to allow for wood expansion.
2. Install locking-studs, clean them if used, lube with lip balm (so important!), and set action then tighten grub screw & then the stud again to lock real tight.
These locking studs have a U-shape pivot and provide a better return so do replace any V-studs! Be sure it also has anchors that have a metal base to them else it won't work! To change these (I needed to on a '04 Jem7VWH) means cutting the paint surrounding it - but it will be covered up for any flaking.

Simple - BTW the modern trems dont have a sharp knife edge. They just need the above to work perfect. My Jem7v was 80% at first until these steps made it 100% no bull!

Re: rg prestige 2550z doesn't stay in tune

Hi

First of all I would like to thank all of you for your answers. The strings are stretched in and the stud locks are installed. The guitar isn't brand new, I have it for about a year (so the factory setup was somewhat redone by me and also the strings changed a few times and the locking nut was always locked properly).

I guess the guitar always did that, but hadn't really noticed it (the difference is somewhere between 30-50 max) because all the strings get sharper or flatter, so the difference between strings was negligible for my ear. Only when I tried to play with a record, I noticed they were a little flat.

I will try the lip balm thing as I understand it works wonders. I don't understand the last bit: "These locking studs have a U-shape pivot and provide a better return so do replace any V-studs! Be sure it also has anchors that have a metal base to them else it won't work!".

Could you please explain again?

Thanks!

Re: rg prestige 2550z doesn't stay in tune

OK firstly I mentioned the locking nut - I meant the screws that hold the nut onto the headstock. It can be loose as it says here in step 5.
http://www.ibanezrules.com/tech/setu..._stability.htm

Then read step 5 about bad tolerence trem posts(studs) also shown here: -
http://www.ibanezrules.com/tech/setup/fat_knives.htm

If the guitar is post '03 it probably wont have a metal based anchors or Inserts: part 2LE2-A (which the stud post screws into) a locking-stud needs a metal base for the inner grub-screw to push against - thus lock it. Don't make the mistake of trying to lock the grub-screw without there being a metal base. Tap the 1.5mm allen key into it to test if you hear metal. So it's the same as a cup shape (with a small hole in it's side for machining) instead of a tube they now use.

Read and understand everything listed on the above site. It's all you must know.

Re: rg prestige 2550z doesn't stay in tune

that's weird man.

i play my 2550z with the ZPS bar in for a few reasons.

1. i can't get the trem level with the studs with 10s using the default springs.
2. i bought heavy guage e-gen springs to get the trem level but then it goes out of tune when you pull up.

so i just play with it in ZPS mode. it stays in tune perfectly. i don't know why.

Re: rg prestige 2550z doesn't stay in tune

It's reccomended to use 4 springs with 10s.
