It’s like typing. I grew up learning 10 finger pumping style in 2 languages. Iphone typing taught me to type at a decent speed with 2 thumps and iPad expand that to 5-6 finger typing, that skill’s transfer to the manual keyboard.
I found myself blasting away with my index/ middle and thumb on each hand, lol.
If I find myself in a similar situation and I can’t properly bend one of my finger I may stick a slide on that finger and explore the possibility of using slide on the bass. It will be very unique.
