Well I've been having this problem, that I have just now started to notice, that every time that I play a couple of power chords at medium to fast speeds, my pick gradually slips away from my fingers. Anybody have any suggestions to remedy this problem?
hand work outs
some people like to put holes in their picks which can give you a more secure hold. I use picks with small grooves that help prevent slipping. Just try a few different picks and see what works for you.
try using a thinner pick.
You can also try holding your pick at an angle so that there's less resistance when you're strumming.
stick a bit of blue tack on the pick to give you more grip
Holes will work, usually. One guy I knew put a groove in each side and tied thread around. Lots of variations but replacing your picks when they get too slippy is a good tip.
Happens to me to, it's probably sweat though
you can always see how those gripped picks work for you
