Distinctly Noticeable Difference
Disclaimer: I buy this through my local guitar shop over Sweetwater just out of convenience. Anyways, I'm out of this right now and will head to the shop tonight to pick more up. This thing does a fantastic job at applying the right about of lubricant for the neck and strings. I feel like a completely different player when I play after apply Fast Fret. I definitely recommend this to everyone. Your sound will stay brighter longer, even after your strings age. I also think this makes the strings last longer.
