It's all about technique and the style of guitar that you play. If you were classically trained, a fixed pinky is definitely a no no. Classically trained guitar players are trained to use their thumb, 1st, 2nd, and 3rd fingers. This was the way I was taught, and used this technique for all sorts of styles of play for years. The only draw back for me was finding a way to switch between finger picking for comping, and then a pick for a soloing within the same tune.ok i know pinky planting isnt very good but when finger picking does like the same rule apply if your using your thumb and index finger to pick?
