ALright what exactly is double thumb stuff many of you talk about and does anyone have exercises or any way to get used to playing with 3 fingers and how long does it take to get used to it?
My view of Double Thumb is that it's a slapping technique where you slap down with the thumb then use the thumb while in the down position to pluck the string on the way back up. It's also called the thumb pluck, which I believe is better because you can pluck up with the thumb without necessarily having to slap beforehand. A useful technique either way.
double thumb and 3 finger help
