The TASCAM 424-S Studio Cassette is a genuine high bias type II cobalt oxide cassette specifically engineered for outstanding output (4db louder than standard Type II cassettes), low distortion, and unmatched musical clarity when used with TASCAM Portastudio cassette recorders. Industry leading specs like high coercivity for superior storage capacity and almost double the retentivity of standard cassette tapes for enhanced imaging of your recordings ensure your recordings will be higher-fidelity and stronger than ever. The tape formulation was engineered and tested specifically in recalibrated and restored vintage TASCAM Portastudio workstations and stereo recording decks. The 424-S Cassette has the same specifications of the Master 424 Studio Cassette, but without the gold collector reels. The TASCAM Portastudio opened the door to home recording over 40 years ago and was THE sound for thousands of albums over the decades, from Bruce Springsteen's Nebraska to DeWolff's TASCAM Tapes. The TASCAM Portastudio's legions of fans and users range from Lady Gaga, Wu-Tang Clan and Beck to Bootsy Collins, Beastie Boys, and the Mars Volta. With vintage TASCAM Portastudios selling at a premium price on the used market, TASCAM is proud to provide the gold standard for the cassette medium.
