I am 72 years old. I bought two new basses. A Jackson Concert in white and a Ibanez gsr200 in black. Have cases for both, straps, a 25 watt amp and a tuner. I am working on online tabs and have paid for 5 lessons with a teacher over 5 weeks. My left fretting hand is not cooperating. Actually, let's blame it on the fingers. They don't want to work together. I can play the intro to "Let's Groove" by EWF with one finger and I'm not far along with anything else. I do love the bass and thought that with only 4 strings it could be easier to learn. Apparently, I was wrong. I'm kinda serious about this when I say that I would love to be able to play one song before I die. GnR, Marvin Gaye, Rick James, Isley Brothers, Parliament Funkadelic or as James Brown would say, "Whatever it is, it's got to be funky"! I'm thinking that I do not have a proper set course to learn this instrument ; like I'm trying a little of this, try a little of that and get nowhere overall. Maybe if someone here had once been in my place and is now a great player and could offer some direction would be great ! For me, quitting is not an option. I see myself playing "Welcome to the Jungle" or "Got to Give it Up" one day !!
