One artist who moved between guitar and bass all night long, in one body of work. Bruno Bacci’s baritone was built for exactly that idea, and this page is our homage to the player who embodied it.
Bruno says it plainly: Prince would have been the greatest baritone testimonial of all, a musician who played both bass and guitar, sometimes seemingly at once, and made a whole band out of one pair of hands.
That is the heart of the Leonardo dual output: two independent outputs, guitar and bass, from a single instrument.
This is a tribute, not a claim. Prince passed in 2016 and never played a Bacci. But if the dual output had existed in his hands, the low end and the top end would have come from the same silhouette on stage.

The Bacci Leonardo carries two real, independent signals wired into the wood. Split them to two amps and one player becomes a whole low end and a whole top end, at the same time.

“Prince would have been the best baritone testimonial of all, playing both bass and guitar.”Bruno Bacci
Prince is the dream. The living proof is a generation of players who reach for a Bacci baritone to cover more ground with one instrument, from funk to fusion to modern jazz.
Bruno Bacci’s baritone guitars have been inspiring a whole generation of top guitar players, including Cory Wong, Mark Lettieri and Matteo Mancuso. With this, he’s part of developing a whole new musical canon.
Jamie Gale, Boutique Guitar ShowcaseI’ve played the Bacci Leonardo Baritone and the build quality is really off the charts.
pmjos, BasschatA pretty extraordinary instrument is this baritone. Such a brave move to break away from iconic guitar shapes.

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.

▶No. This page is a homage. Prince passed in 2016 and never played a Bacci. Bruno Bacci names him as the artist who best embodies the dual-output idea: one player covering guitar and bass.
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.
