Special 100 Year Anniversary series AM-1100 Concert

Featuring Voci Armoniche's revolutionary  BlueStar® reeds

The AM-1100 has achieved what many thought to be no longer physically possible; what petosa considers to be the art of perfection. The AM-1100 belongs to a class of its own, setting the standard by which all other accordions are compared. Uniquely and individually handcrafted from the highest quality materials through four generations of craftsmen, no accordion is as powerful in sound nor will endure the test of time like an AM-1100. The AM-1100 Concert is designed for the discerning professional artist featuring unprecedented versatility. A uniquely dry-tuned violin register captures the pure tone of a non-chambered voice with the harmonically vibrant resonance of a chambered voice. From the haunting harmonic complexity of the chambered bassoon to the unique, unison violin register; a profound and distinct clarity to each note.
BlueStar®

In 2022, the year of our 100th anniversary, the BlueStar® reed has replaced our finest handmade reed as the top of the range, it exceeds in acoustic and functional potential. The new BlueStar® voices are a natural result of a new vision in the art of crafting reeds. They are the conclusion of a path of observation, study and improvement by third generation Lorenzo Antonelli. They are not considered handmade; nor a variant, or a restyling. The BlueStar® is a new voice, different from the voices of the past and those of today, because it contains substantial innovations and differences.

Compared to the handmade reed, the BlueStar® reed has specific improvements:

1) Enhanced overall timbre and functional homogeneity resulting from today's most advanced computer measuring software to enhance precision of the tongue shapes. The precision between tongue and plate has been raised to the highest possible degree.

2) Stability of the final tuning while preserving the important chargepoint.

3) Resistance to fatigue failure, improved by the thermal bluing treatment.

4) Thermal bluing of the tongues also improves the steel in its metallurgical properties, consequently improving the functional characteristics of the reeds (usability, ductility, dynamics, homogeneity).

BlueStar® is a natural evolution of innovation and technology; improving on the best characteristics of the finest handmade reed, resulting in the most refined, dynamically responsive and powerful reed produced today. When joined together with special, precision-modified reed block chambers, the result further optimizes the characteristics of this new voice. petosa is pleased to be in partnership with Voci Armoniche to bring this pioneering concept to market - now available in select petosa models.
