Rene Martinez Graphit All Guitar Lube Set

I use this lube on saddles, nut and string retainer on all my guitars and basses.

Especially for the ones who bends often or uses tremolo systems, this will make your tuning a lot more stable than before.

Application is very simple. Provided toothpick is just enough for it. And a tiny amount is usually more than enough. Then just wipe the residue with the provided little cloth.

I have 10 guitars and after using it for longer than a year, the tube is still almost full. That and the improved tuning stability are how I justify the price.

Only cons is that it is a heterogenous solution. So, over time it will release a liquid and you need to shake it a while before using.

Overall, I appreciate Rene Martinez's efforts and he deserves the every penny he makes on this lube! Hope it stays in the market forever.

This guitar lube is one of the best things that I've bought for my guitars. Use it every time you change strings on the nut, string guide and bridge saddles. Without it, you're scared of using your tremolo because you know that you guitar will probably be out of tune after. With it, you can use your trem as much as you want and the strings hold their tuning. The stratocaster trem is really where this products excels.

The Rene Martinez isn't cheap and you only get a small tube, but you only use a drop - and I really mean a drop on the parts of your guitar that is in contact with the strings. I think one tube will last for a few guitars over a few years and many string changes. If you work out how much that costs in effect, you wouldn't even think about it. They use it at the Fender Custom Shop, so it's definitely good enough for me.

I had been having issues keeping my 5 string bass in tune and would often have a lot of minor tuning adjustments to do prior to each session.

I decided to use this on the nut slots, bridge saddles and through body ferrules when I changed the strings. I now note that my bass remains in tune between sessions. I use a strobe tuner for tuning purposes so it's easy to see the pitch accuracy of each string and they are now always perfect and adjustments are less frequent.

Granted the string set may also be contributing to the stability, however, I feel that the lube in the nut slots is likely an essential part of the improvements since there is now no string binding with the nut material (bone, in my case).

My conclusion is that this a simple and effective way to improve tuning stability, definitely would recommend it.

Looks fine at first. Expensive for what it is, but should last a lifetime, works wonders - what's the catch you may ask? The catch is that the bottle will not and can not stay in one piece, the weak spot is the bottom end that's heat/pressure sealed (poor design), I guess they expect you to buy it again after their poorly made bottle breaks. Now my expensive guitar case is full of hard to clean graphite lube, and I'm out of 19 euros. Otherwise a wonderful product that really helps the tuning stability, but I will not buy from this manufacturer again, and if you value your money I suggest look for products that come in at least decently made bottles.

I've tried this and Big Bends Nut Sauce, and I keep coming back to this one. The Nut Sauce is alright, but I seem to need to apply it more often for the same feel.

It's no coincidence that Rene Martinez knows a thing or two about keeping a blues bender's guitar in tune, having been Stevie Ray Vaughan's tech. I'm no Stevie Ray, but I do 3-fret bends all the time, so no guitar that hasn't been prepared before can stay in tune 10 minutes after I begin playing it.

I'll only buy this from now on. It's no-nonsense and it just works.
