So this is one of my best (cheap part) purchases so far.
I modified my Fender Wayne Kramer acoustic guitar with a few things, and by far this was one of the best things I did.
There are absolutely no cons installing these pins on ANY acoustic guitar. But the PROs... It gives you a tremendous amount of sound quality boost, and sustain.It changes the ease of string change (no more broken plastic / synthetic / wooden / bone / shark-tooth pins ever), no more pins sliding out, gives your guitar a massive gain in string / body contact, meaning noticeable resonance transfer change (positive change), increased sustain, and there's a decent amount of plus frequencies in all the ranges from high to low. I think this modification has far the most impact on any of my guitars modded ever. You can not go bad with changing pins, and for this price it is surely worth a try, even if you (for some unknown reason) do not like to outcome (but why?). Reviewing the above it totally seems that I work for these guys at dAndrea, but I can only talk superlatives of this product. Something so simple can do a lot here.
+Toss up some decent Schaller keys with it, and you have a new and better acoustic guitar. Oh and I totally forgot to mention the bad*ss looks it gives. 5/5!
