Thanks for the recommendation, Bob. Would the 30-button Jackie be able to produce most "normal" chords? I find most of the songs I play use G, G7, D, Dm, D7, Dsus4, C, A, A7, Am, E, Em, E7, F, Bm, B7, Bm7.
Maybe the better question would be, what chords would not be possible on the 30 button jackie? Sorry if these questions aren't very good, I don't have formal music training, and may not understand what I'm asking even.
