"I WAS READY TO DESTROY EVERYTHING.
BECAUSE THAT SOUND, THAT HAD NEVER EXISTED BEFORE
– Bruno Bacci, Bacci Guitars
THE SOUND DID NOT EXIST BEFORE.
THE LINE.
THE GUITAR THAT BREATHES LIKE A VIOLIN.
“This one made me stop talking.”
50 INSTRUMENTS Limited edition. Numbered. 50 guitars. Then it closes. 45 remain available.
Bruno could make more. He won’t.
Limits are what give meaning its gravity.
This is the sound Bruno spent eight prototypes finding.
Deep. Dynamic. Alive. The hollow body resonates like an acoustic. Custom Kloppmann pickups capture it without mud. Clarity AND warmth—impossible, but real.
10 years to discover. 11 months to build yours.

The FIGHT
THE QUESTION THAT WOULDN'T LET GO.
Is there anything else we can take off?
We spent years debating material, simplicity and shape. This is about the removal of everything that isn’t sound.

Walnut
“Precise, sandy and bluesy”
Material Research
TOSCA NOCE™ (Walnut)
DARK • WARM • COMPRESSED
Walnut responds fast and controlled. The attack has texture, that sandy grain that gives the sound character. Midrange stays focused, sustain stays musical and every bend, vibrato and dynamic shift remains precisely where you put it.

TOSCA ACERO™ (Maple)
BRIGHT • ARTICULATE • TRANSPARENT
Mahogany and spalted maple respond tight and direct. The attack has snap and precision, that firm clarity that gives the sound definition. Midrange stays focused, top end adds upper-mid presence and every note separates cleanly even under gain.
Visually: spalted maple tops are naturally patterned. Each one is distinct.

KLOPPMANN
22 MH-MH Kloppmann Custom Bacci Mini-Humbuckers
Custom-voiced sets have been designed and engineered specifically for each Tosca’s skeletal chambering system.
FRETS
JESCAR
Stainless steel frets (55090) designed to resist wear over long-term use while maintaining a smooth surface reducing friction and supports consistent feel across the fretboard.
TUNERS
K-TAR
Ultra-light locking tuners engineered to reduce overall headstock weight while improving tuning stability, helping maintain balance and minimise pitch drift during extended playing.
PERFECTION ISN'T A SOLO ACT
When you spend 10 years developing prototypes, you don’t call vendors. You call the two specialists who’ve spent 40 years refusing to settle. Kloppmann wound 14 pickup versions for Tosca. Eri Goshen spent 7 years on subtractions and proportions. This is what our passion is made of: finding others who understand to develop beyond our own capacity.
MASTER LUTHIER
BRUNO BACCI
Cremona violin-making school, 2012. Trained where Stradivari had built violins 300 years earlier. Chose electric guitars instead. Then he heard a sound that didn’t exist.
Bruno Bacci builds electric guitars like a sculptor builds form: slowly, deliberately, obsessively.
In his workshop in Tuscany, wood, tension and silence become one voice. Every instrument begins as an idea and survives years of refinement until it feels inevitable. And through every personal and professional hardship, one thought kept him alive: the possibility of building Tosca. That promise kept his passion lit when everything else went dark. Today, he builds for players and collectors who recognise rarity, nuance and a sound that feels like it has never existed before.
“This instrument has a new sound, a sound born from an idea I had. It was made for the future of music, not for playing old music.”
Over a decade creating a sound that didn’t exist yet. Bruno started with violin construction principles—the archtop, the resonating body, internal bracing connecting top and bottom. Then Eri Goshen brought harmony to curves Bruno had drawn instinctively. The collaboration was difficult: convincing an architect that sound matters more than design. When the Les Paul was born for jazz, it became a rock icon. Bruno doesn’t know what Tosca will become. He only knows it wasn’t made for collectors—it was made for the future.
Designer
ERI GOSHEN
Tel Aviv Stock Exchange. Hashalon railway station. Israel’s most iconic structures. Then he bought a 13th-century estate in Tuscany, Italy and started designing products that didn’t exist in either country.
Architect Eri Goshen is responsible for some of Israel’s most significant urban projects. Since returning to teaching at Shenkar School of Design and Engineering, he’s been bridging two worlds: consulting Italian companies on product design and advising Italian towns on urban development. He writes regularly on architecture and design, sitting on various professional and public committees across both countries.
“Somebody said once that beauty is when you cannot take anything off it anymore. You came to the limit. That’s what I tried to do in seven years with Bruno.”
Seven years to design an instrument when you can’t predict the sound. Eri Goshen spent a career as an architect knowing exactly what the result would be. With Tosca, that control disappeared. The goal was to minimize everything until only the essential remained—to leave the stage for the music, not for the eyes. The sound that emerged wasn’t designed. It was discovered. Neither acoustic nor electric, but something new entirely.
Pickups & Electronics
ANDREAS KLOPPMANN
Gibson PAF ’58. Fender Strat ’56. Legendary pickups from the golden era. Then he spent two days unwinding each one by hand and started making pickups that could recreate sounds that no longer existed.
Kloppmann pickups Wound specifically for the TOSCA hollow chambers. Each coil is measured for DC resistance and inductance under controlled climate conditions.
“I saw the prototype of the guitar and I heard how the character of the basic guitar was, and then I thought, what’s the right way to bring this to life as an electrical signal?”
For nearly a decade, the challenge remained: bringing acoustic and electric sound together without piezo systems. Tosca’s pickups were developed with Andreas Kloppmann in Germany to translate the instrument’s natural resonance rather than replace it. Twice a week, Kloppmann and Bruno connect on FaceTime, checking how the guitars develop. Understanding the complete situation first—the character of the wood, how it resonates, how to carry that signal forward without losing what makes it alive.
TIMELINE

THE NUMBERS OF 10 YEARS SEARCHING FOR PERFECTION
10
Years of Research
A decade of research into sound and vibration, joined by architect Eri Goshen to reimagine the guitar’s design through architectural thinking.
7
Prototypes
Full instruments, hand-carved and wired, reduced to splinters because the mid-range resonance was 2dB off the mathematical ideal.
50
Limited Edition Units
The only 50 instruments that will ever bear the Perfection Concept stamp. Non-repeatable, numerically controlled but hand-perfected.
HOW IT IS BORN
THE RITUAL
The 11-month creation cycle.
01. The Conversation
Direct consultation with Bruno Bacci.
02. Material Selection
Ultrasound testing of candidate timbers.
03. The Carving
300 hours of manual structural refinement.
04. Delivery in Tuscany or shipment
Personal handover and final setup adjustment.
Tosca's effect
Unscripted reactions from players encountering Tosca for the first time and old friends along the way.
2018 “Dionysus”
Bruno Bacci & Cory Wong
“It’s not just a clean tone. It’s structural clarity.”
Cory Wong played the first TOSCA prototype when it was still called “Dionysus.” His signature snap required rethinking the entire physics of the string-to-body connection.
The Destruction Protocol
“Ok, enough talking. You have to give me this guitar.”
That’s how Cory closed his one-on-one with Bruno the moment he tried TOSCA FIRST prototype.

What You Need To Know
FAQ
What makes TOSCA different from production hollow-bodies?
Production hollow-bodies are designed to be built. TOSCA was designed to be heard. Eleven months of hand construction, custom components developed over ten years, a body geometry derived from Cremonese violin-making tradition. The difference it’s in what the instrument is capable of doing that no production line can replicate.
Can I try TOSCA before I commit?
The Bacci Experience™ - Limited Private Event.
You can hold TOSCA in your hands. In the room where it was built. Bruno will walk you through every choice - the wood, the structure, the sound. You play it. You feel it. You understand it.
Some people come to try it. Most leave knowing exactly which number is theirs.

What happens after the 50th instrument?
This limited edition closes. This is the final version, fully hollow, Goshen design, Kloppmann configuration. After #50, it’s done.
Why does it take 11 months?
TOSCA is built entirely by hand, one instrument at a time.
Each set of woods is individually selected and matched for balance, resonance and long-term stability. The full hollow structure requires extended shaping, assembly and calibration, with no part of the process rushed or automated.
Every component is fitted, adjusted and voiced specifically for the instrument being built. There is no standard production line, no interchangeable bodies and no parallel assembly.
Before delivery, each completed TOSCA is personally played and evaluated by Tommy to ensure the instrument reaches its intended voice.
The eleven-month build time reflects this approach:
time dedicated to precision and quality, listening and refinement rather than speed.
What are payment methods?
A 50% deposit initiates the ritual.
The remaining 50% is completed upon final inspection before delivery or visit in Tuscany.
Payment in three instalments is available.
