About the luthier
Siccas Luthiers was founded by brothers Mirco and Manuel Sicca, who have dedicated their lives to the art of classical guitars, inspired by their late father Mario Sicca. Mario excelled not only as a soloist, but also as a respected professor at the Stuttgart Musikhochschule, and as a passionate luthier and collector. His deep love for the instrument continues to guide their vision. Rooted in the experience behind Siccas Guitars, a reference for hand-made instruments by the world’s finest luthiers past and present, Mirco and Manuel set out to create guitars that reflect the same high standards of sound, aesthetics, and craft. This vision led to the creation of Siccas Luthiers, a project shaped by unique designs developed in-house by a team of experienced luthiers and players.
About the guitar
The “Synthesis” model by Siccas Luthiers is a double-top concert guitar that seeks to unite modern construction techniques with the tonal ideals of the Spanish tradition. Both the outer and inner layers of the soundboard are cedar, joined by a nomex core, which contributes to its high responsiveness and tonal uniformity. This matched-wood configuration results in a voice that feels organic and connected, with a wide dynamic range and substantial volume that remains centred in a warm, vocal character.
The nitrocellulose finish plays a subtle yet important role in preserving this tonal character. Thinner and more acoustically transparent than modern poly finishes, it reduces damping while still offering adequate protection, supporting the guitar’s resonance and clarity.
The cedar version of the Synthesis model excels in projection and sustain, with a direct, assertive treble line that responds with very little input. Its ease of activation and immediate feedback make it highly playable across a range of dynamic contexts. This is a concert-ready instrument, capable of both refined lyrical phrasing and commanding presence, while maintaining tonal focus and a responsive, fluid articulation.

Regular care extends the life of the instrument
Even with careful use, a classical guitar may gradually change in appearance or respond to unstable storage conditions. Have a close look at your guitar regularly and be attentif to changes. If your instrument is suffering from its environement, it will let you know.
Protect Your Guitar: Handle with Care
Be mindful when touching your instrument with greasy or unwashed hands: any skin contact is a small attack on the varnish. Of course, a guitar is made to be played, but taking a few precautions helps preserve its beauty: wash your hands before playing, wear long sleeves, and avoid unnecessary direct skin contact with the body of the instrument.
Pro tip: Avoid playing with a button-up shirt, heavy jewelry, or a belt, as these can scratch the guitar. Also, make sure your guitar case is free of any objects that could damage the instrument during storage.
String care
A good habit to adopt is wiping down your strings briefly after each playing session. This small action significantly extends their lifespan and helps maintain a consistent, comfortable feel under your fingers.
Most importantly, clean strings are essential for keeping your instrument in tune. Corrosion, sweat, and dust can affect the uniformity of the strings and interfere with accurate tuning across the entire fingerboard.
Pro tip: If you're having trouble getting your guitar in tune, it might be time to change the strings. A useful test is to compare the pitch of the 12th fret harmonic with the fretted note at the 12th fret; if there's an unusually large gap between them, your strings may have lost their integrity and should be replaced.
Keep Your Shellac Finish Shining!
Got a guitar with a shellac (French polish) finish? Here's a simple trick: Take a clean microfiber cloth and gently breathe on the surface to create a light mist. Then, softly rub to remove fingerprints, sweat, and grease. That’s usually all it takes to keep it looking great, no products needed!
Pro tip: Every few years, treat your guitar to a check-up with a luthier to keep it in top shape.
Storing Your Guitar: Climate Matters
Your guitar can safely stay outside its case, as long as the surrounding environment maintains 42–55% humidity and a temperature between 18–25°C.
Keep in mind that humidity levels can still fluctuate inside the case, especially during seasonal changes.
- Too much humidity may cause overtightened strings and a dull tone.
- Too little humidity can lead to a bulging top, string buzz, or even cracks.
Avoid placing your guitar near radiators, air conditioners, or windows with direct sunlight.
Pro tip: Always close your guitar case while playing. This helps preserve a stable microclimate inside the case, so your instrument is protected the moment you put it back in.
