Graph Tech PT-7004-00 String Tree

As these ones does not "cache" strings as some metal string retainers, they are good replacement option if you have problem with yours (provided that the nut is correctly cut, otherwise fix your nut first).

Keep in mind that screws are wider than some original ones (Squier and Yamaha Pacifica came to mind), so predrilling existing holes carefully is good start. Especially if you have finished headstock. It will crack, if you try to force wider screws. Don't ask how do I know that.

Really takes the load of the strings in a smooth way. Looks good and seems to not stop the strings from moving with bends and tuning. Recommended

It has a nice texture and doesn't damage the strings at all, and looks rather modern, which could be a good or bad thing. All in all this is good quality from graph tech and recommended

I really like these, they do a great job of keeping my guitars in tune when paired with locking tuners. They are not particularly good-looking and are quite expensive for such little things but that didn't stop me from putting them on all my guitars that require string trees because they really are that good.
I used to have roller string trees on my guitars before but I find these much better and they do not require any lubrification.
Careful not to overtighten the screws, they can brake and, at this price, it's really not something you want to happen!

Got these to replace the cheap pot-metal string trees on a Squier. They do the job fine, but they're a little bit rough and unfinished (visible seams, blobs of excess material, etc.). They can be cleaned up with some abrasive paper, but as there's no real need to change their size (as opposed to, say, a nut), it's a pity that GraphTech don't supply them with this already done. Still, it's not very visible on the headstock, and they do the job of managing the break angle on the higher strings.

A great upgrade to any guitar with steel string trees, 5 stars

It's a highly effective and easy-to-install upgrade for guitarists seeking enhanced tuning stability and string performance. Its self-lubricating design reduces string friction and improves sustain for sure, while its durable construction ensures reliability. This string tree is a worthwhile investment that improves overall playability and enhances your guitar's performance.

These string trees work fantastically to reduce friction behind the nut. Better than roller trees for sure!

Fits perfectly no issues with installation. Really imporved tunning stability and looks great :)

Pretty much the perfect string tree, easy to install, high quality material which lets strings glide under easily.
