I came up playing in Ceili Bands in the lower mid-western USA where I was "volunteered" because I could play piano in the old timey boom chuck style. When I picked up the guitar at about 13 or 14, I continued to play the bass lines--but with my thumb on the lower strings. The old fellers demanded that I play the bass lines cause it reminded them of when somebody would be playing the boom chuck Piano in sessions "back home on the Ould Sod," or when the button accordian player played the bass notes on the low chord buttons. I still play guitar in this style, no pick, especially when playing Irish Music. The 6 string has only 2 strings more than the Bass. The walking bass lines are right under your fingers in the chords, which are mostly open chords. It is something to think about if you really love the Music that much & want to be a part of it.
