I'm a few months into the rest stroke technique and while I can definitely play louder, it's come at the expense of a very noisy tone. There's a lot of extraneous sound, either from the string I'm coming to rest against, or a background buzzing of open strings. This isn't due to mechanical problems with the guitar, but is clearly noise that I am introducing.
Have other people had the experience of a "noisy" period when learning this technique?
What can I do to get a cleaner tone? Of course, the answer is always practice, practice, practice...but I'm wondering if there are any specific techniques to try. For instance, in the book you discuss brushing the strings with the backs of your right hand fingers to get a sense of where your hand is in space; do you also do this to damp out strings that shouldn't be sounding?
