In 1982 Tom Scholz, founder of pioneering hard rock band Boston, designed and released the Rockman X100 headphone amp through his company Scholz R&D. It was more than just a headphone amp, with recording console connectivity and several tone tweaking featuresand built-in effects - the X100 became the secret weapon in the studio that would go on to define the polished, chorus-laden sound of 1980s arena rock. The MXR Rockman X100 revives the signature sonic character of the original amp in a stomp box form. The MXR design team captured the same crystalline cleans, crunchy harmonics and shimmering modulation of the original. With the same four tonal presets, carefully calibrated compression and bucket-brigade chorusing, this all-analog recreation also features both mono and stereo modes and optional external mode switching for an enhanced user experience. Buffered bypass. Cannot be powered by a battery. Supplied with AC adaptor (ECB003).
