I haven't spent a lot of time on the street. I played an outdoor New Years Eve set once. It was between 30 and 40 degrees and raining and much too cold to be playing as I learned the hard way. But I managed to tough it out until midnight with frozen fingers and uncontrollable vibrato. It was a life lesson I for one won't forget. Check the weather before agreeing to outdoor shows.
See life on the street section...lol
I play a Taylor 110CE as my main instrument and I have a Washburn WA90CE as a backup. I do from time to time break my trumpet and chock out a few notes. I guess you might say my voice is my instrument as well.
