Griffin Technology has introduced its new GuitarConnect Pro accessory for the iPad, iPhone, and iPod touch. GuitarConnect Pro connects to the device using the Dock Connector port, and adds a standard 1/4 inch instrument jack, with a built-in gain control, to the device. It is compatible with any instrument that has a 1/4 jack, and with most Core Audio apps, including Apple’s own GarageBand. Users can monitor the audio by connecting a pair of headphones or speakers to the device’s built-in headphone jack. Griffin’s GuitarConnect Pro accessory for the iPad, iPhone, and iPod touch is available now and sells for $80.
