If you can’t play without a pick, we should talk. Mastery of the pick is essential to the well-rounded player, but it’s only one tool; your right hand is a whole tool box. Fingers hitting strings can get SO many colors, from tons of different funk styles to screaming rock (I sometimes play shredder solos with fingers) to Jazz to Country to Acoustic and Finger-Picking, such as Travis. Rhythmic articulation, cleaner arpeggiated lines, more aggressive accents; it’s all there. Don’t underestimate the capabilities of your fingers and thumb with no pick. And of course, I do teach this.
