Line6 Sonic Port, in great condition, only used for practice in a smoke-free home. Comes with the original box and manual, and with two cables - one with a Lightning connector for newer iOS devices, and one with the old-style 30-pin connector for older devices (this one is unused). This is a very flexible interface for iOS devices (iPhone, iPad, iPod), allowing you to process or record the signal in various apps, like Line6 POD, GarageBand, Moog Filtatron, PositiveGrid apps (possibilities are virtually endless). It has two inputs (1/4" for bass/guitar, and 1/8" stereo for other audio sources) and two outputs (1/4" mono/stereo for amps and other devices, and 1/8" stereo for headphones). It's powered by the iOS device, so it doesn't need batteries or other power supplies. More info at line6.com. $35, shipped to CONUS. PayPal only.
