Nut Sauce Lil Luber 0.5cc by Big Bends

This is great and has helped with tuning stability on all my guitars. I was thinking about docking a star for the price as it seems very expensive for the amount you receive however it works so well and you only need to apply a small amount so I do think its worth the money and would recommend it to anyone who plays guitar

Thought I'd try this stuff after hearing good things, now I can't do without it, solves tuning issues so much better than old fashioned graphite or other methods. It won't save you if your nut isn't decently cut, but if it is it will really help with strings returning to pitch after bends, etc. Tiny tube, but lasts a surprisingly long time as you only need the smallest amount per application, in fact the less you use, the better it seems to work.

Bit expensive but works well

Works very well and loving it. Have bought my 3rd one now as getting very hard to get hold of. Have many guitars and it is the right stuff to use please believe me I swear by it ^^

Works well. You only need a very small amount per slot / saddle so it should last a few applications

Pricey but works well ,my Les Paul sticky G string is no longer sticking

I use it to keep guitars in tune - especially Gibson-style guitars..very necessary if you perform. Per gram its expensive!

I thought I'd try this one to fix the *PING* every time I adjusted the tuning (especially on the G and B string) which indicates that the string gets a bit stuck in the nut. Alternatively, I'd go to a luthier and have either my nut fixed or a new nut cut (graphtech). Well... I don't think I need to do that now. After applying the sauce, the problem is essentially fixed. And I have a feeling (probably all in my head) that even the vibrato has a nicer tone to it too. I like this sauce. So, for £11, I'd say its a rather worthwhile investment to increase tuning stability and avoiding the annoying *PING*! Not sure I believe the claim that the sauce increases string life from 1100 attacks to 12000, but hey... even double would be ok in my book :).
