The TX Underfacer is like The TX Interfacer but designed to go under an angled pedal board.  Use Underfacer to take care of all your input, muting, tuning, summing, isolating...     SPECIFICATIONS

TX Underfacer:

• Designed to fit under an angled pedalboard, preserving pedalboard real-estate.
• Handles input, muting, tuning, summing, isolating, and phase correction needs.

Master Mute:

• Mute signal before reaching amps using mute pushbutton on The TX Underfacer.
• Remote control of master mute available with RMT.

Summing:

• Two summing modes: Stereo Sum and Split Sum.
  • Stereo Sum: Left and right inputs merged, sending the same signal to both left and right outputs.
