So my bass teacher wants me to play bass with all 4 fingers like a real man rather than 2 because the ability to do so would balance out my right hand and make playing with 3 a million times easier. So I learned how to use my wrist to help my pinky out and this technique is evolving to the point where I use the right fleshy side of my pinky to sound the note (and thus in my rolls my wrist does a somewhat circular motion). First question - Anyone here play with 4 fingers? I'm also thinking about incorporating the thumb slap with the 4 fingers to make things more versatile. Please tell me your experiences and what you are able to do with this technique. Second question - Worst blister ever on the right side of my pinky. I haven't had a blister since I started playing bass about 5 years ago. What are some tips to take away the pain or blister so I can play with no pain? Right now i'm just playing through it waiting for that callous to develop.
