Widely called one of the finest guitarists alive. On the Bacci baritone, he says, he doesn’t really miss the bass player.
The Sicilian virtuoso plays without a pick, a fluid fingerstyle technique that rewired what the instrument can do and made him one of the most talked-about guitarists in the world.
On the Bacci baritone his lines gain body and vocal weight low down while every note stays articulate. At NAMM his virtuosic homage to Paul Gilbert, performed entirely on his signature Radiance Celeste baritone, took Guitar World’s Best Guitar Solo of 2024.
It is the case for the baritone in modern jazz: harmony with its own foundation, phrasing that breathes below the guitar.

Mancuso’s Radiance Celeste is an Officina baritone: elegant, articulate, voiced for clarity across the register.

Guitar World, Best Guitar Solo 2024
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,” a nod to how much low-end body the instrument delivers.
A baritone is a guitar with a longer scale length, roughly 27″ and up, tuned lower than standard, usually B to B or A to A. You play it exactly like a guitar, it simply lives in a deeper register between guitar and bass.
Most players tune B to B, a fourth below standard, or A to A. Every Bacci is built to your preferred scale, gauge and tuning.
No. The chord shapes and technique are identical, just on a slightly longer neck. Most guitarists feel at home within minutes.
A single baritone with two independent outputs, guitar and bass, so one player can deliver both voices at the same time, live and in the studio. Read the Dual Output Story.
