The IK Multimedia iRig Acoustic Stage is a versatile digital acoustic guitar pickup system that may be used onstage or in the studio. Simply place this high-performance MEMS microphone and standalone preamp in the soundhole of your guitar and you're ready to record. Use the Blend and Phase controls to tweak the sound of the iRig Acoustic Stage with your existing guitar pickup system through Aux input. A strong feedback suppression mechanism eliminates unwanted feedback, while inbuilt DSP allows individual tone tuning. When connected to a Mac, PC, or iOS device, this audio accessory not only produces an extraordinarily realistic acoustic tone, but its 32-bit AD/DA conversion also produces great quality.
