Featuring a Buzz Feiten tuning mode — a Korg exclusive!

This Korg DT-7 Tuner has a large, easy-to-read LED meter, super-accurate tuning in all modes (rackmount accuracy in compact tuner), a built-in buffer amp to eliminate "loading" effects normally found when playing through a tuner, a "sound out" mode for silent tuning that is remotely switchable (from a footswitch), especially bright LEDs, and a built-in mic. It tunes both in a normal mode or in the Buzz Feiten mode for guitars, a patented tuning that adjusts or tempers the standard tuning slightly to set up in the Feiten system.

Korg DT-7 Tuner Features:

Two types of tuning mode can be selected: chromatic (for tuning normally tuned instruments) or Buzz Feiten.
Large LED-type meter and seven-segment note display ensure optimal visibility, making this the perfect choice for any guitarist or bassist.
Wide tuning range [A0 (27.50 Hz) to B7 (3,951.07 Hz)], allows tuning of a wide variety of instruments including five and six-string basses.
Compact, easy-to-view design, stable even when placed on an amp.
Buffer amp between the INPUT jack and BYPASS jack eliminates any tonal coloration.
A convenient Sound Out mode.
Built-in mic allows use with acoustic guitars.
