The AW-LT100T is equipped with a small clip that's optimized for attachment to the bell of a trumpet, cornet, or trombone. You can easily position the tuner for best visibility, allowing you to stay aware of your own pitch while you practice.
Korg AW-LT100T Trumpet, Cornet, or Trombone Tuner
Instead of the button cell battery used in many previous clip-type tuners, the AW-LT100M / T / V uses a single AAA battery that's easy to obtain and has a higher capacity. An alkaline battery allows an amazing 100 hours of continuous operation. With long-life design that's more than 12 times as long as previous models, it delivers extremely high cost-effectiveness. Even if you leave the tuner powered-on during your performance, you can continue using it for an extended time without having to replace the battery.
