The MC-403 Power System—the latest collaboration between Bob Bradshaw and the MXR design team—is truly the ultimate power supply. The MC-403 powers more types of pedals and electronics at one time than any previous power supply unit available. High quality, high performance toroidal transformers insure quiet operation with superior performance capabilities. Designed for maximum flexibility, the MC-403 can be used on pedal boards or rack mounted in a single rack space with the front mount bracket (included). All multi-tap outputs are completely isolated, linear regulated, and short-circuit protected to insure reliable operation. Enclosed in a heavy-duty housing, the MC-403 is designed for years of rugged road or studio use.
