Korg has announced two additions to its family of tuners: the GT-4 Guitar/Bass Tuner and DT-4 Chromatic Tuner. Each offers three tuning modes, built-in condenser mic, better than +/-1 cent detection accuracy, compact design, plus large note name display and bright rotating LED display to indicate pitch.
The DT-4 can tune from A0-C8 (88 notes) with a calibration range of 410 Hz â€“ 480 Hz (1 Hz increments). The GT-4 is optimized for guitar/bass applications, supporting seven-string guitars (7B-1E) in guitar mode, and six-string basses (Low-B â€“ Hi-C) in bass mode. The GT-4 also includes Korgâ€™s Quinta-flat tuning mode, which supports drop tunings up to five semi-tones down.
The GT-4 and DT-4 offer three convenient tuning modes:
- Strobe mode The tuning LEDs rotate when a pitch is detected, and stop when the instrument is in tune. The LEDs rotate clockwise if the instrument is sharp or counter-clockwise if the instrument is flat.
- Mirror mode LEDs indicate the pitch of the input. The instrument is in tune when the â€œbrightâ€� LEDs and the â€œdimâ€� LEDs line up with the center indicator. The LEDs will move to the right of center if the input pitch is sharp, or to the left if it is flat.
- Meter mode The instrument is in tune when the LED is aligned with the tuning guide in the center, as on a conventional needle-type tuner.
The GT-4 and DT-4 have a built-in condenser microphone, making them ideal for tuning acoustic guitars and basses as well as other acoustic instruments. The tuners feature compact black bodies, have 1/4" input jacks, operate on two AAA batteries and have an auto shut off feature to prevent unnecessary battery consumption.
