Scale length is the single biggest choice on a baritone. It decides how low you can tune, how the strings feel, and how tight the bottom end stays.
Scale length is the vibrating distance from nut to bridge. On a baritone it governs two things at once: string tension and low-end clarity. A longer scale holds more tension at the same pitch, so notes stay tight and articulate instead of flapping.
Around 27–28″ is the sweet spot for tuning comfortably to B, with a feel most guitarists adapt to immediately. Push to 30″ and beyond when you want to sit reliably at A or lower, or run heavier strings: the bottom gets tighter and cleaner, at the cost of a slightly longer reach in the low positions.
Because every Bacci is made to order, the scale is not fixed. Bruno builds the neck to your target tuning, string gauge and hand, so the instrument is optimised for how you actually play.

Bruno Bacci is a Tuscan luthier with a background in metallurgy, woodworking and design. A guitarist first, he became a builder after a hand injury and trained at the violin-making school of Cremona, where Stradivari had worked three centuries earlier.
He does not begin with a shape. He begins with the sound he wants to hear and builds the instrument around it, testing each piece of wood by hand as though in conversation with it. Every Bacci is made individually and is backed for life by Bruno himself.






When I play it, I don’t really miss the bass player.

▶Baritones generally run from about 27″ up to 30″ or more, versus around 25.5″ on a standard guitar. The longer scale is what keeps low tunings tight.
Yes. At the same pitch and gauge, a longer scale carries more tension, which improves clarity and tuning stability in the low register.
If you mainly live around B, ~28″ is ideal. If you want A or lower as home base, go longer. Bacci will advise based on your tuning and strings.
Yes. Every Bacci baritone is handbuilt to your chosen scale, gauge and tuning, with Dogal Custom Bacci strings matched to it.
