How to Tune a 5-String Bass? | Low B Essentials

Standard 5-string bass tuning is B-E-A-D-G from lowest to highest, with all strings separated by perfect fourths.

If you just picked up a 5-string bass, the first thing to know is that the familiar four strings of a standard bass are all there — E, A, D, and G — with one thicker string added underneath. That Low B changes everything, and tuning it correctly is the difference between a tight, punchy low end and a muddy rumble that fights the kick drum. Getting the tuning right on all five strings takes about two minutes once you know the pattern.

Why The Low B String Makes Tuning Different

The five-string bass extends the range of a standard four-string down by a perfect fourth. The Low B string is tuned to B0, which sits at approximately 30.87 Hz — a frequency that’s technically below the threshold of precise human pitch perception for many players. That’s why relying on ear-only tuning for the Low B is a mistake; at that pitch, small errors are hard to hear, and even a slightly-out B string will clash with the rest of the band. A good electronic tuner is the only reliable way to nail it.

Each string pair follows the same relationship. From lowest to highest, the standard interval between adjacent strings is always a perfect fourth — the same interval as the E-A-D-G spacing on a four-string bass. Learn the Low B position once, and the familiar tuning logic remains intact across all five strings.

Step-By-Step Tuning For Standard B-E-A-D-G

Start with an electronic tuner clipped to the headstock or plugged into the bass, depending on your setup. Tune the Low B string first, since the rest of the process builds upward from it.

• Step 1 — Tune the Low B string to B0 (approx. 30.87 Hz) using your electronic tuner. Let the tuner settle before adjusting.
• Step 2 — Fret the B string at the 5th fret and match it to the next open string, the E string. The two notes should sound identical.
• Step 3 — Repeat the 5th-fret check up the neck: fret the E at the 5th fret to match the open A, fret the A at the 5th fret to match the open D, and fret the D at the 5th fret to match the open G.

This 5th-fret method works because each pair of adjacent strings is a perfect fourth apart. Once the tuner has the Low B in place, the check verifies each relationship and catches any intonation or tuning drift.

One useful tip from experienced players: some prefer to tune all five strings with the tuner first, then do a final pass on the 5th-fret pairs to polish any offsets that crept in during the first sweep. The process stays the same — the sweep is just a final confirmation.

String Gauges And A Proper Setup For 5-String Basses

Guitarists moving from a 4-string bass to a 5-string often notice the heavier Low B requires more tension, which is precisely why the.130 gauge is standard — it keeps the string stable and articulate at B0.

The other strings follow the same measurement standard, so checking the entire set at the 12th fret keeps the bass consistent up and down the neck. When you install new strings, aim for 3–5 wraps per string, with the wraps going downward toward the headstock. After installation, stretch each string gently and retune to pitch — the strings will settle into place and hold the tuning far better than a fresh pair pulled straight to pitch.

Setting the Low B to the right action isn’t just about comfort. If the string sits too high, the intonation can shift noticeably as you reach up the neck, and the lower register will feel stiff. A properly set 7/64″ action at the 12th fret gives a clean balance between fast playing and a stable tuning.

Alternate Tuning: E-A-D-G-C

Some players prefer E-A-D-G-C instead of the standard low-B setup. This tuning replaces the low B with a higher C string, extending the range upward instead of downward. It’s the go-to choice for solo bassists and players who want brighter lead lines and more access to the upper register without moving all the way up the neck.

When switching between B-E-A-D-G and E-A-D-G-C, note that the string gauge and setup change accordingly. The Low B.130 is replaced with a lighter string suited to the higher C pitch, and the action may need a slight adjustment to accommodate the difference in tension. Use the same electronic tuner approach for the new tuning, pairing the tuner with the 5th-fret check on each adjacent string pair.
