These devices are made from salvaged trumpets and other brass instruments, with assorted machine parts. I designed and built these units to amplify and direct the music (or other sounds) being played through my iPhone and iPad, while using no external power source. It's basically a trumpet iPhone amplifier.
After 13 years of making these brass smartphone amplifiers, I have decided to phase them out, and concentrate more time on other projects and media. For now, I will no longer make new items for sale to the general public. If you need a replacement dock, I still have some, and will try to help however I can. Thanks for 13 great years!
