Hi I have been playing guitar off and on for about 15 years. No matter what I do or practice, I can't seem to play more than one string up and down strokes fast while palm muting on the bridge. The upstrokes basically just sounds percussive and has no tone. My pick also gets caught on the upstroke which I believe is the problem.

If anyone could please direct me to any videos or steps to resolve this.

It would change everything for me.

Thanks CD
