Have no experience as a busker on the street. How I wish I had done that.
Playing LIVE, I forgot the song lyrics & chords quite a few times.
Nothing to shout about. My instruments are: a Yamaha APX 8A Acoustic Electric, a Yamaha Classical CG150, a Fender Squier Stratocaster Deluxe Hotrails, a Roland Audio Interface, a Soundtech stage Mic and a Denford mixer.
