Query: very, very disapointed

At one time "Sony" had a very good reputation for quality products.This cassette recorder was anything but a quality product (mechanically,everything worked just fine). Sound reproduction was abysmal -- far worsethan poor! A very loud "hissss" overrode the recording -- even when I usedan external microphone. I did not expect a 4track recorder, but what Igot should be an embarrassment to any manufacturer. Shame on you SONY!!PC Taylor
