Steve also uses a lot of thumb movement (especialy on the upstrokes) but i don’t don that.
To me the benefit is that you have a more stable grip without having to squeeze. I still hold the pick with the tip of my index finger for having good control.
I have seen players (like Troy himself) placing the pick more on the joint part of the indexfinger. But In order to do that you will have a lot of indexfinger sticking out on the side of the pick which i don’t like because i feel i loose some control.
Please share some thoughts on this?
