How do you tune a bajo sexto with a chromatic tuner?

To tune a bajo sexto using a chromatic tuner, first ensure the tuner is set to standard tuning. The standard tuning for a bajo sexto is typically B-E-A-D-F#-B, from the lowest string to the highest. Pluck each string one at a time and adjust the pitch until the tuner indicates that the note is in tune, aiming for the center of the display. Repeat this process for all strings, making fine adjustments as necessary to achieve a perfect pitch.
