Best pedals and effects for the solo player
I'm looking for recommendations on what kind of pedals to use for a person who is mainly playing alone or with one other player (most likely piano or vocals). Right now I know I'm interested in a looper pedal (for creating bass lines to solo over), chorus (for fattening the sound), and octave up pedals (to mimic the guitar/bass duality). Any recommendations for these types of pedals? Are there any other types of pedal that I would find useful that I'm leaving out?
