Korg Gt-4

The GT-4 is a dedicated guitar/bass tuner that automatically detects an instruments pitch which offers simple operation. With a large note name display in the center and red LEDs that rotate in a circular pattern, it is a revolutionary tuner with superb visibility.

It supports seven-string guitars (7B through 1E) in Guitar mode, and six-string basses (Low-B and Hi-C) in Bass mode. While compact, it instantly indicates the pitch with the high precision you expect from Korg. The built-in high-sensitivity mic supports tuning of acoustic guitars as well.
