Finger pick mostly, never liked using picks. When playing electric I use a thumb pick that wraps on my thumb then can pinch it if needed to hold it tighter for harder strums I guess you would call it, and I love the 12 string, there is nothing that sounds like it. Also all SOLO is if your either playing totally solo, or doing a solo with a band, when you play you use a pick, or finger pick a guitar, when a chord is needed you strum it, ect and so on. I am sure this is what you were getting at, just very non explanatory.
SO! In short! LOL! I use a pick when playing electric and when on the acoustic I finger pick. :) lol
Would you like to buy a 1969 Strat?
(Got one in the closet, that has never had strings on it. Ever!)
