I really need help anyone. I know what a hammer-on and pull-off is, but like others who play Tears in Heaven, the distinct sound is NOT loud enough. Like when i pull-off you can barely hear it. any advice on hammer-ons and pull-offs? thanks.
You need to 'pluck' the strings when you pull off. Pull down (towards the floor). If you lift you finger it doesn't work.
The word 'pull' in pull-off is very important; you have to pull the string down slightly with the finger you're pulling off, it's quite difficult when you first try, especially on acoustic but it should become natural after a while. As for hammer-ons you're probably doing them right you just need a bit more power to make them sound, but that comes as your finger strngth increases.
