Baritone, Bass VI, or bass?

01The confusion

Three low instruments, often confused.

Three instruments sit in the space below a standard guitar, and almost everyone blurs them together at some point: the baritone guitar, the Bass VI, and the bass guitar. They look related, they all go low, but they are genuinely different tools, and knowing which is which saves a lot of wrong purchases.

Here is the clear version, from a workshop that builds in this register every day.

02The baritone

A guitar, tuned lower.

A baritone guitar is a six-string guitar with a longer scale, tuned down, usually to B or A. You play it exactly like a guitar, the same chord shapes and technique, it simply lives in a deeper register. It is not a bass; it is a guitar that has moved down.

Reach for it when you want guitar playing, chords, melody, riffs, in a darker, heavier register, without changing how you play.

The instrument

One instrument, both voices

The Bacci Leonardo is a baritone with a dedicated bass voice on a second jack. Handbuilt to order in Tuscany.

03The Bass VI

A six-string, an octave down.

A Bass VI is a six-string instrument tuned like a guitar but a full octave below, E to E at bass pitch. It bridges the two worlds: guitarists feel at home on the six strings and familiar shapes, but it speaks in bass territory, with a distinctive clicky, tic-tac character.

Reach for it when you want a true low instrument that a guitarist can play intuitively, or that classic baritone-guitar-meets-bass twang. It is closer to a bass in pitch than a baritone is.

04The bass

The foundation instrument.

A bass guitar is usually a four or five string instrument, tuned in fourths, built to be the harmonic and rhythmic foundation. It is a different instrument with its own technique, not a guitar you play low, and nothing else quite replaces it for holding down the bottom.

Reach for a bass when you need the foundation, full stop. The baritone and Bass VI colour the low end; the bass defines it.

Think of it as a ladder. The baritone is a guitar that stepped down a few rungs; the Bass VI is a guitar that stepped all the way to the bottom; the bass is the floor itself, a different instrument built to be the foundation.

Baritone colours the low end, Bass VI bridges to it, bass defines it. A dual-output baritone does two rungs at once.

05The Bacci angle

And when you want both.

There is a fourth option worth knowing. A dual-output baritone like the Bacci Leonardo carries a guitar voice and a dedicated bass voice at once, on two jacks, so one instrument can give you baritone guitar up top and a real bass line underneath at the same time.

It does not replace a dedicated bass for a bassist, but for a guitarist who wants both registers from one instrument and one performance, it answers a question the other three cannot.

→Common questions

Baritone, Bass VI and bass, in short.

What is the difference between a baritone and a bass?

A baritone is a six-string guitar with a longer scale tuned lower, played exactly like a guitar in a deeper register. A bass is a separate, usually four or five string instrument built to be the foundation, with its own technique. A baritone is a guitar that goes low; a bass is a bass.

What is a Bass VI?

A Bass VI is a six-string instrument tuned like a guitar but a full octave down, E to E at bass pitch. Guitarists find it intuitive, and it has a distinctive tic-tac character between a baritone and a bass.

Is a baritone guitar the same as a Bass VI?

No. A baritone is usually tuned to B or A, only a fourth or fifth below a guitar, while a Bass VI is a full octave down at bass pitch. The baritone stays closer to a guitar; the Bass VI sits closer to a bass.

Can a baritone replace a bass?

Not on its own, a baritone is still a guitar. But a dual-output baritone like the Bacci Leonardo adds a dedicated bass voice on a second jack, so one instrument can cover guitar and a real bass line at the same time.

Which should I choose?

Choose a baritone for guitar playing in a deeper register, a Bass VI for a guitar-tuned instrument at bass pitch, and a bass to be the foundation. If you want guitar and bass from one instrument and one take, a dual-output baritone is the answer.
