Is not miraculous - but almost!

I use FastFret a very long time, mainly to rauszuholen at guitar with old strings a little more sound.
The best feature in my opinion, that can be the strings clean well - but you have the "rubbing off" with the cloth a squeaking bear ^^
I get more guitars in their hands, where for years no strings were changed. Before I abtue as garbage, because I do not always buy new strings for a guitar that does not belong to me, I can at least reduce the rust with FastFret something and make the strings better playable.
The course benefits the sound, and it can also be good results on nylon achieve.
Kindly, the stuff is also good for the Fingerboard - visually and care.

If I strings so treat regularly at his own guitars, they live longer. Even braided strings will eventually reach a state where you have to maintain a little to get it.

Even if it sounds weird: I also like the smell of FastFret.

A product that you can try it quiet. Dries, however, at some point from - who has only a guitar, and used only now and then FastFret, I recommend keeping in a truly airtight sealed vessel.
