JAM from Apogee is a pocket-sized, plug and play interface that brings the legendary sound quality of Apogee to the iPad, iPad2, iPhone 4, and Mac. It allows the guitarist or bassist to interface with the guitar amps and effects in Apple's GarageBand software or other compatible applications.
The digital converter features PureDIGITAL technology which delivers high quality guitar sound for practicing, recording, or just jamming. A status LED on the top panel indicates whether JAM is connected properly while also functioning as an input level indicator. For optimum sound a rotary style wheel is located on the side for easy thumb access.
There's no difficulty involved in setting up or configuring JAM. Just plug it in, open your favorite software, and play away.
