iRig Acoustic is an innovative, patent-pending, acoustic guitar microphone pickup that installs in seconds that you use to perform live and record with on an iPhone and iPad. iRig Acoustic provides professional high-quality sound, simple installation and freedom to play and record everywhere. And with the AmpliTube Acoustic companion app, you’ll have in the palm of hand the world’s first and most powerful acoustic tone sculping and refinement studio for playing anywhere, any time.

Sound quality of studio mics — only better

There’s no argument that the best acoustic guitar sound reproduction comes from placing a high-end condenser studio microphone in just the right position in front of the guitar. iRig Acoustic, when used with AmpliTube Acoustic, is designed to perfectly replicate that ideal mic placement and accurately capture the full frequency range, tonal character and complex harmonics and overtones of acoustic guitars. It's able to do this thanks to the combination of its uniquely designed microphone enclosure, which combines the latest MEMS (MicroElectrical-Mechanical System) microphone technology with an omnidirectional polar pattern, placement of the microphone just inside the sound hole where the output is optimal and the sound is very detailed and focused, and the “calibration” process that optimizes the guitar sound like it is being miked externally with a high quality studio microphone. These technologies combine to capture the "complete picture" of an acoustic guitar — every vibration and sonic interaction — unlike piezo-electric pickups or magnetics that just capture the vibrations of the body top or strings. Simply put, iRig Acoustic delivers a pure and full representation of an acoustic guitar's tonal characteristics.

More on MEMS

iRig Acoustic utilizes a MEMS microphone to deliver amazingly real acoustic sound. MEMS (MicroElectrical-Mechanical System) is the cutting edge of microphone technology — you are most likely already utilizing this technology without even knowing for many smartphones use MEMS technology mics. These microphones are very efficient and offer outstanding reliability and audio capture.

They deliver a very precise compensation and accurate flat frequency response while being very resistant to mechanical vibrations that produce unwanted sounds, thus providing a very clear, open tone. In addition, MEMS mics are very durable and stable so iRig Acoustic will deliver consistent, detailed and focused sound performance after performance.

Easy installation – clip on, plug in

iRig Acoustic offers you the convenience of being easy to install (or remove) on any guitar — no modification of any instrument is required to use iRig Acoustic. It simply securely clips on to the rim of the soundhole of an acoustic instrument and you’re ready to play. Because you can easily install and remove it, you can use iRig Acoustic on all of your acoustics, even during the same set!

True mobility

What truly makes iRig Acoustic unique is the fact that it delivers studio-quality sound AND allows players to freely move around on stage or in the studio without feedback or altering the sound. This is virtually impossible to do when utilizing traditional acoustic miking techniques in the studio or in live performance situations.

Headphones or Line Out

iRig Acoustic plugs into your device headphone/input jack with a standard 1/8” TRRS cable that also allows you to monitor your performance thanks to the female stereo output jack placed on the in-line cable. Plug your headphones into this jack for private practice and monitoring, or you can line out to a mixer or powered speaker for full stereo acoustic performance.
