Allora Chicago Series instruments, like this AAS-580 Chicago Series alto saxophone, provide professional quality and features at an affordable price. They are perfect for advancing students, adult enthusiasts and professional musicians. Their "Expanded Bell" design provides punch and presence especially suited to jazz and rock, but also great for "classical" players who prefer a somewhat bigger sound. The AAS-580 is available in dark gold lacquer or unlacquered brass. The unlacquered version will develop a natural patina over time for a one-of-a-kind vintage look.
