I have been playin electric guitar for three years now and over this past couple of weeks i have been wanting to learn how to pick fastly.to be able to do this i have started basically using one note and picking it (downstroke then upstroke repeatedly) and trying to gradually increase the tempo of that note but i have serious bother because whenever i start at a reasonable speed and then try to make it quicker, my upstrokes just hold me back from going any faster becauses the guitar pick keeps on gettin caught in the string on the way up instead of picking it.it seams like i havent got good control on my upstrokes when trying to pick rapidly.any suggestions?
