I've learnt Gospel Blues on electric guitar, simply because I didn't want to try to deal with learning a new song and struggling with acoustic slides at the same time, but now I have come to play it on my acoustic (steel string) it can be hard to make out the sound of the slides sometimes because of the scratchy noise created by sliding down steel strings. I've tried it with more pressure, with less pressure and nothing seems to help. The problem seems to be worse with the three finger slide than the one finger barre, but they're all a problem.
Maybe it's just a case of my not plucking the strings loud enough that the notes drown out the noise of the strings? Has anyone else had this problem?
