If you loved iRig s versatility you ll love iRig 2 s new adjustable gain dial which works with its built-in 1/8 TRRS output connector to give you a true plug-and-play experience with your iPhone iPad iPod touch or Mac. Volume levels vary from instrument to instrument and from device to device. And while the original iRig provided superior sound it was limited in that you were unable to customize the input gain level to your particular setup. With iRig 2 you get an input gain dial that gives you the power to ensure high-quality sound in every situation. This means that you ll be able to perform at your best no matter whether you re connecting a wailing 3 humbucker electric guitar or a jazzy archtop to your iPhone. Likewise its 1/4” instrument input works with your guitar bass or any line-level instrument. Just plug into it like you would into a stompbox or amplifier. It’s as simple as that.
