Tuning the low B on a five-string bass
The added B0 string extends below standard four-string bass and needs especially clean isolation. tuner.love keeps B0 first in the five-string selector and maps it to the instrument's measured physical string and peg.
A strong harmonic can momentarily dominate a very low fundamental, so use one deliberate pluck and let the detector follow the sustain. Selecting B0 locks Auto mode to that exact target.
Four clear steps
How to tune accurately
- 1Mute E, A, D and G, then pluck the low B near the center of its speaking length.
- 2Let B0 sustain and make small key adjustments while the cents display stabilizes.
- 3Continue low to high through E1, A1, D2 and G2.
- 4Recheck B0 after the neck has settled under the completed tuning.
Reference: A4 = 440 Hz
