Awesome Tuner & Metronome

This is a great tuner. Easy to use and the additional features such as the metronome makes it a great practice tool along with customizable presets to save your favorite settings. I own the previous version (StroboFlip) and this is a nice improvement.

I originally bought this product through a third party supplier of Amazons. The unit was covered in a white powdery substance that I wrote and asked Peterson directly about. They informed me the white powder was not normal and the serial number on this unit was originally sold to Latin America. It was really great to see a manufacturer so concerned about not only their product but their customer. I immediately returned it to Amazon and purchased a BRAND NEW one from Sweetwater. The unit is perfect. Does everything the manufacturer claims. I read a couple of the negative reviews stating the unit was cheaply made. Nothing about this unit screamed cheap to me. I checked the harmonics on my guitar with my clip on tuner. They showed dead on, however I could hear they were slightly out. This unit immediately showed they were out, and with the strobe just how much. My guitars have never sounded better. This unit should be in every performing musicians gig bag or on their work bench. For guitar players everywhere, thank you Peterson for a great department, and for your excellent customer service.

Very accurate tuner. Charges on computer USB didn't think I would like that but I haven't had to buy a battery yet and the thing stays charged for ever. Very good for setting intonation. May seem pricy for a tuner but it's well worth it. I highly recommend this product. Thanks to Ben Robinson for all you do. Love Sweetwater

Sweet tuning in toxic environment?

Pedal steel players who are trying to sweet tune your instrument in a noisy environment - this is the answer. Just dial in the setting for E9 tuning and jack your instrument into the tuner and you've got it. Also, if you play other instruments with altered tunings, just dial in the appropriate setting for whatever you're playing. It's a very nice tool.
Music background: Mystified by many stringed instruments for decades


This gadget is a necessary expense for the pedal steel guitarist as well as the non-pedal steel player. It has all the "sweeteners" for existing pedal steel tunings in addition to a few non-pedal ones. Emmons and Newman are no longer with us, but they have left us a legacy with the sweeteners in the Strobe Tuner.
