I've been playing bass in punk bands for about 15 years. I have always played with a pick. I took guitar when I was 14 and was drilled for months on alternate picking and I'm extremely fast and efficient at it. To the point that I can not play all downstrokes (frustrating!) I've wanted to learn how to play with fingers but I get so annoyed that I can't play the easiest song. I get bored and stop. Any suggestions that will help me learn to play finger style while keeping my interest?
