How do I read a strobe display?
Adjust your instrument until the pattern is as close to still as possible. Strobe displays are 'real-time' and extremely precise. They require very fine tuning adjustments to stop the display because the frequency/pitch of any instrument is never totally stable.
You'll quickly learn to read the display, make the most precise adjustments and appreciate the high resolution that only a Peterson provides.

I often tune my acoustic instrument in a loud environment. What's available to help with that?
A Peterson TP-3 clip-on tuning pickup is a very versatile device with a 1/4" connector that can be clipped onto any portion of the instrument that vibrates, such as the headstock of a guitar or the bell or lead pipe of a horn.
A Peterson Pitch Grabber Mobile Tuning Clip utilizes a 1/8" connector for use in mobile phones or tablets with software tuners.
For instruments with a flat resonating surface, you can use a suction cup tuning pickup to reduce ambient noise interference.

- Presets wrap upward, but not downward, in all modes.

Select the sweetener and hold the selector knob in and rotate it until the Note indicator says C which is the default root. Release the selector knob and rotate it to the root note you desire.
