ok, maybe not mastering, but really getting it down. intonation, being creative, doing little tricks that sound great, cool weird noises, being able to play without having your eyes glued to the neck, etc. i had a fretless a while ago but rarely played it cuz it was crap. my new acoustic has got me obsessed though, but i'm not progressing as quickly as I'd like to. i landed a new gig that i could really use the bass on but i'm nowhere near confident enough yet. being consistently dead on key is actually what i'm having the most trouble with. any tips, ideas, exercises that will speed up the learning process??? thanks in advance.
