Specialized tuning.
With its lively up-tempo sounds that feature various stringed instruments, bluegrass music is enjoyed by people all over the world. Korg has now created a dedicated tuner for bluegrass instruments ---
The BA-40 allows you to tune bluegrass instruments including- banjo, fiddle, mandolin, resophonic guitar-in addition to standard guitar and bass. Perfect fifths are supported for fiddle tuning. The LCD meter-type display provides better than +/-1 cent accuracy, and features excellent visibility on stage or in the studio to ensure that you can tune easily and accurately.

Accurate tuning.
With a detection range of E1@bbbbb (30.868 Hz) to C8 (4186 Hz), the BA-40 covers the entire range of instruments used in bluegrass music, and also allows you to adjust the pitch up or down in semitone (half note) steps so that you can use sharp/flat tunings relative to the standard tunings of these instruments. You can even tune your guitar with a capo still attached. Markings on the meter allow you to use a tuning reference in a range of 430 Hz to 450 Hz.

Sound Out mode.
The BA-40's Sound Out mode uses the internal speaker to play a reference tone of the correct pitch for each string of the instrument you're tuning. You'll be able to tune more accurately by using both eye and ear as well as train your sense of pitch by repeatedly listening to the reference tone.

Bypass function.
The BA-40 provides an output jack that can be connected directly to your amp/speaker system. This allows you to leave your instrument connected to the tuner while you perform so you can easily check tuning at any time. By using the optional CM-100L contact microphone you can tune accurately even in noisy environments.

Auto Power Off function.
The Auto Power Off function conserves battery life by automatically turning the power off when the unit is not in use for ten minutes.
