This is a little cheaper than some other (ahem) brands. I only have one Ibanez guitar and only one guitar with a locking trem (a Floyd thing made in Germany by Schaller a very long time ago), but looks to me like it's got all you need to set up your whammy bars.
Because I hate locking trems (I believe they suck the tone, and there is more surface-to-unit contact in PRS, end of) some of the benefits of this little guy might go unused by me, but if you're one of those Vai types, then basically, you need this.
I got this mainly for purposes of set-up, and perfect intonation, and it has everything I need. With a decent strobe tuner and this, you can set your axe up pretty much professionally. That'll cost you at least 30¤ in a guitar store. So this within the space of a year will pay for itself. So learn how to change strings perfectly (it's quite easy these days, even with locking trems), get one of these and take the power back!
Oh yeah, and it's by Ibanez. Not my chosen brand but millions can't all be wrong. A fine piece of kit.
