But what makes it more versatile than any other micro amp is that it features the iRig circuitry so you can plug your iPhone or iPad into it with the included TRRS cable.Dual Mode Operation – AMP/DEVICEWhat makes iRig Nano Amp so unique is that you can operate it in two different modes: AMP & DEVICE. In AMP mode it’s a standalone amp for impromptu practice anywhere. In DEVICE mode you use it as an interface and amp for your iOS device. Plus, in both modes you can use the built-in speaker or hook up an external speaker cabinet – up to a 4×12″ cab – for more volume and tonal clarity. iRig Nano Amp is the most versatile, feature rich micro amp in the market and provides you with outstanding value and performance.AMP modeiRig Nano Amp operates as a straight up guitar amp and features a British tone stack circuit with gain and volume controls for practice on the go. Simply plug in your guitar to the 1/4″ guitar input, adjust your volume and gain settings, select the output type NORMAL/BRIGHT and rock out anywhere you happen to be. The British tone circuit delivers sparkling clean tones at lower gain settings and a cascading wave of overdrive when cranking the gain to the upper limits.DEVICE modeiRig Nano Amp is also an interface and output for your iOS device thanks to its integrated iRig circuit.
