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 bluegrass tuner for a wide variety of bluegrass instruments

The Korg BA-40 allows you to tune bluegrass instruments including- banjos, fiddles, mandolins,and resophonic guitars-in addition to standard guitars and bass guitars. Perfect fifths are supported for fiddle tuning. The LCD meter-type display on this bluegrass tuner 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.

*Even if the pitch is within range, detection may not be possible for instruments that produce large numbers of overtones, or for instruments that have very fast decays.

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 your eyes and ears 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 banjo 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.
