Question: Is it feasible to use looper pedals at solo harp gigs?
Yes, it is, and I definitely recommend it. Using a looper can make you freer and give you the chance to be multiple instruments, all in one. You can tap all around the harp, looking for different sounds and rhythms to record, or find a cool and simple bass line and then improvise on them with nice melodies. At the very beginning, it can be frightening. You have to practice until you are confident enough to have fun. But even with really simple lines and harmonies, you can achieve a wonderful result, and the audience loves it! In addition, you can experiment a lot with sounds, overdubbing different effects that you can extract from the harp, creating a totally new sound-universe in a concert.
