Standard tuning for a four-string electric or acoustic bass is E1-A1-D2-G2, tuned in perfect fourths. It maps exactly one octave below the lower four strings of a standard guitar, establishing the low-end foundation for modern rhythm sections across all genres.
A needle answers "what is the average pitch right now?" A multi-harmonic strobe adds an extra layer to the tuning visualization by showing several harmonics at once, so you can fine-tune more confidently to fractions of a cent.
