Derringers proudly bring you PreSonus:

"We live and work in Baton Rouge, Louisiana, Cajun Country, USA. It's a rich jambalaya of jazz, blues, rock, zydeco, metal, folk, and Christian music that constantly fills each of our lives. We record in our bedroom studios, run the sound systems at our churches, and immerse ourselves in the rich local club scene.

Each morning we come to a wonderland disguised as our office building, complete with a custom-designed professional recording studio and first-rate live-sound room. There, we design, test, and experiment with ideas for new products—and we perform and make records because music really is our life."
