All models have steel accordion-style reeds.
Their mellow tone makes them ideally suited for song accompaniment. The Button Box is proud to annouce our own line of concertinas, made here in New England. The notes of a scale alternate between the left and right sides. The number of buttons varies from 30 to 70, but 48 is standard. They are very smooth and agile instruments, originally designed for classical music, but well-suited to folk music and chordal song accompaniment.
