Left hand speed techniques
hey all! i currently decided to start playing for a death metal band and i cant for the life of me keep up on some parts with my left hand. alot of my prior experience as a bassist comes from folk,rock,punk and some jazz stuff, so this speed is a little different for me lol. i was wondering if someone could give me tips, or a video link or anything to help. my fingers start to bumble around and i cant get down 3 strings fast enough while moving multiple frets. just wanting to up my skill aswell as keep my mind challenged. any suggestions???
