I know a quite a few musicians who are obsessed with audio gear. To the layman it must seem a little weird. There's no real mystery why we place so much emphasis on our gear. No matter how well you play you only sound as good as your PA. A quality system adds to the impact of your music and the enjoyment of your audience. The solo performer has an additional qualifier as the rig has to be easy to transport, setup, and strike for one person. If you care about such things, my gear is outlined below.

I have been building and refining this rig over the last three years for ease of transport and setup while retaining good audio quality. I believe the performance of this setup to be equal to if not superior to PA systems 2 to 3 times its size and weight. Given the compliments I receive on the quality of the sound people tend to agree. I can setup in a very small space and, unlike a full band with a live drum kit, the sound can go from whisper quiet to 'in your face' loud.
