GHS Fast Fret is a string cleaner/lubricant/conditioner. It could have been a placebo effect, but I swore by this stuff in my early playing days. I felt like I could glide the strings quicker and that my tone from old strings on my acoustic guitar sounded brighter.
Any subtle differences in feel and sound that you notice as a beginner is awesome, and using fast fret will give you that. It may just be the pick me up if you or your strings are starting to dull. Try it!
I still use it, or a comparable product, to this day.
