Peterson divers Pitchgrabber

This tuning mic attaches easily and safely to any musical instrument to capture the note with its piezo mic to send it directly to your tuning application. It plugs into your mobile device's mini-jack input to completely isolate your instrument's sound and create direct audio input to your app, even in noisy environments. It is compatible with Android devices that have a 3.5mm mini-jack input and all iPhones including iPhones 7 and above with their supplied Lightning to 3.5mm jack adapters (in this case, be sure to plug the Pitch Grabber into the iPhone adapter before plugging the adapter into your iPhone).
