ok so im trying to learn how to sweep pick but i notice a big problem right away. As i take one of my fingers off a string it rings a bit like a quiet pulloff or something. How do i fix that?
Um, you're going to hate me, but practice. Sweeping is an advanced technique, it's not something you can just "do"...you just have to work at it.
Get your fingers to mute the string as you take them off the frets
