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

Great for smooth operation of guitar. If you hear clicks and pings when tuning up you may need to use this under the strings at the nut.

Bit expensive but works well

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.

Helpful aid to improve tuning guitars.

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

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