Does a brass slide sound better on an acoustic or does a stainless steel slide sound better?? OR!! does it really matter at all?
here you go, ask "two string". all i can tell you is ull want high action, and dont mash the frets.
Oh, it DOES matter!! Metal slides have a bright, tinny sound. Glass has a more subtle sound and is more forgiving. Dude from the Allman Bros. used a glass medicine bottle..they still make them. The old skool blues players will tell you nothing beats a wine bottle neck.
Buy yourself some Heineken, drink it before or after you cut the neck off (I recommend after), and then have fun...
