Watch the Hybrid Picking online guitar lesson by Robert Renman from Blues Booster
I often use my pick + middle & ring fingers when I play. I find it is easier to play with dynamics when you use this technique. This can be used for many useful effects and styles of playing. I often play single notes with just my middle finger, because the tone sounds so much better when using your fingertips, compared to using a pick. Still, there are times when you need a pick, such as faster single note runs, for example. I recommend you experiment with using a pick, and using no pick at all. In some ways, you can get the best of both techniques, using this hybrid pick approach!
