I've recently started going through some acoustic blues lessons at jamplay.com. The instructor plays with a thumb pick. I had gone through the first 8 lessons using a standard pick but the latest lesson requires plucking the 3rd and 6th strings simultaneously for the turn-around. So, I bought a thumb pick and I really can't stand using it. It seems you can only pick down unless you put it on so tight that it cuts off circulation to your thumb. I also had alot of trouble adjusting to the height difference between my thumb and other figers and also maintaining a consistent volume between the strings. I've actually worked on keeping hold of a regular pick while I pluck the 6th string with my thumb.
My question is, will I be crippling myself by not learning to use the thumb pick? If so, does anyone have any tips on getting comfortable with it?
I forgot to mention that I was initially playing the latest lesson with no pick at all but my thumb became very sore.
P.S. Just to clarify for everyone, I'm still holding the pick between my thumb and pointer finger but twisting my pointer and pick out of the way a little and plucking the 6th string with my thumb, not the pick and the 3rd string with my middle finger. Almost like I would do it if I wasn't holding the pick at all. I'm able to switch to this and back to normal picking without any pause so it's working pretty well.
