Players of both acoustic and electric instruments can rest assured— a built-in electret condenser microphone and ¼” input jack provide excellent connectivity. Gone are the days of having to carry extra batteries and tripping over power cables during a performance!

This tuner is rechargeable via computer bus or outlet power, and its large, circular screen is easily viewed in both the darkest and brightest environmental conditions.

Features such as Auto Off, easy menu navigation, tripod mounting capability, over 90 of our Sweetened Tunings, tone generation ability via built in speaker, and a headphone output jack round out the package.

Finally, future-proof updating and parameter editing is made possible by the tuner’s unobtrusive side-mounted USB jack. And for those feeling exceptionally adventurous, this tuner can be upgraded to also feature our super flexible Body Beat metronome option, along with both audible AND tactile mode operation.

Hear the beat or feel it…the power is in your hands. This tuner is fit for the most discerning of players and technicians for sure!
