"Madder Horn" is an Analog Tele-Phonographer made from an old horn similar to what you would find on an early automobile. The base is made from old machine parts. There are three small gears that spin, sandwiched between two larger gears. The main shaft is a handle from an old shop vise. The stainless steel dock fits iPhone 4 and iPhone 4s, and is removable / replaceable for upgrade.
