Tuning your guitars and other instruments is stealthier with tDeltaLab’s new NT-100 Ninja tuner. This tuner attaches to the back of your guitar’s headstock using DeltaLab’s versa-mount base. The base provides semi-permanent mounting via a high-stick silicone backing that is safe for most poly and nitro finishes.

When not in use, the tuner folds flat so that it’s hidden behind the headstock and invisible to the audience. When you flip it open, its auto-on/off feature engages, illuminating an extremely bright fisheye LED readout. A detachable 360° swivel cup ensures you can view the display from any angle.

To use the Ninja with other instruments, simply pop it out of its versa-mount base and into the included clip-on base.

The Ninja can be calibrated between 430 and 450 Hz and can detect frequencies from A0 (27.5 Hz) to C8 (4,186 Hz). In addition to the main display, a nine-LED meter provides a visual tuning reference. Red LEDs light when the pitch is sharp or flat, guiding you toward perfect tuning, and when the pitch is in tune, the center LED glows yellow, while the main display illuminates bright green. A low-battery indicator ensures you’ll know when it’s time to replace the Ninja’s 3V lithium battery.

The DeltaLab Ninja is available with a street price of $29.99. For more information, please visit www.deltalabeffects.com or the dedicated Ninja microsite at http://ninjatuner.net.
