In 1982, Tom Scholz—visionary guitarist and founder of pioneering hard rock band Boston—designed and released the Rockman X100 headphone amp through his electronics company Scholz Research & Development (SR&D). But it was more than just a headphone amp—with recording console connectivity and several tone tweaking features and 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 Analog Tone Processor revives the signature sonic character of that headphone amp in stompbox form. Aided by veteran MXR engineer and SR&D alum Bob Cedro, the MXR design team captured the same crystalline cleans, crunchy harmonics, and shimmering modulation as 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.

• CTRL jack allows MODE function to be controlled with an off-board switch such as the MXR Tap or MXR TRS Split + Tap.
  
• FOOTSWITCH toggles effect on/bypass
  
• MODE button cycles through four different tone presets: two differently equalized clean modes with high-power sustain and two distinctively gritty dirty modes.
  
• CLN2 mode: Default setting. Provides a clean, crystal clear tone. 
  
• CLN1 mode: Mid-focused EQ curve. Tuned for a tight, punchy sound.
  
• Edge mode: Moderate clipping. Very sensitive to INPUT
• GAIN adjustments and cleans up nicely at low guitar volume settings.      
  
• Distortion mode: High-energy overdrive and sustain that makes for easy, fluid leads.
  
• VOLUME slider adjusts overall output volume.  
  
• INPUT GAIN slider adjusts input gain level. Increase for a more compressed sound.
  
• CHORUS button adds chorus effect.

• Input Impedance: 700 kΩ
  
• Output Impedance: 1.8 kΩ
  
• Current Draw: 120 mA
  
• Bypass: Buffered Bypass
  
• Power Supply: 9 volts DC
