Built in 1995, the AM-1100 models are 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.  Virtually two accordions in one, the interchangeable Musette reeds offer optimal versatility; including Italian, French, German, Polka, Cajun, Zydeco, Blues configurations and more.
