I think *some* of the crazy guitar purists on this board don't realize that all of us can't afford to shell out $200+ a month on guitar crap and spend over $1000 on every guitar we own.
Cheap college students unite!
Also, I realize that Fast Fret isn't going to work miricles by any means, but it makes the strings feel a little more fresh and sound a little better, and $3 for a bottle that'll last you over a year isn't bad at all. I wish I could afford to restring all of my guitars with elixers every 2 weeks or every time I break a string, but you've gotta be realistic. I'm willing to replace with cheaper strings less often for a marginal amount of sound loss.
