Sales, repairs, and rentals of violins, violas, cellos, and string basses are the core business of A440 in Chicago. Naturally, we have a wide selection of bows for sale to string players of all abilities. Violin, Viola, Cello, and Acoustic Bass strings, cases, and accessories are available at discount prices.
