The Motown D.I. WB-3 features transformers painstakingly reproduced to exactly replicate those used in the original version of this direct box. ACME Audio, in an effort to perfectly replicate the quality and sound of the original Motown D.I., tracked down the original manufacturer of the coveted transformer and enlisted them to start making them again after 35 years. As a result, the Motown D.I. WB-3 is built to the exact specs with the same materials as the originals, and exhibits the same audio character and lack of low frequency magnetic saturation that sets it apart from all similar devices. The limited edition Wolfbox III DI units are sold out - but that same audio character and sound quality has been recreated in this unit. These units are hand-crafted in Detroit and produced in limited quantity.
