The OMB guitar is just like any other guitar, you connect it to the amp through the ¼ inch jack. It can also be used as a regular guitar. The digital virtual band accompaniment comes out of the app. Use the headphone jack on your mobile device or iPad to connect it to an amp/speaker (Regular ⅛ inch aux cable). If your device doesn’t have a headphone jack, use a converter dongle from the charging port to the headphone jack. This way you get 2 channels, one for the guitar and one for the digital accompaniment and can reach a perfect balance.
