Peterson PitchGrabber Mobile Clip-On Pickup
 
The PitchGrabber Mobile tuning pickup easily and safely clamps on to virtually any musical instrument and captures the pitch using its piezo pickup sending it directly to your mobile tuning application. The PitchGrabber Mobile uses the headphone/mic input of your mobile device to completely isolate the sound of your instrument and provide a direct input path to your tuning application.
Perfect for tuning in noisy environments.
Compatible with Android devices using a 3.5mm input and all iPhones including the iPhone 7 series when used with the Lightining to 3.5mm adaptor. Lightning-to-audio adaptor is not included.
