Description:

The TX Underfacer is like The TX Interfacer but designed to go under an angled pedal board.  Use it to take care of all your input, muting, tuning, summing, isolating and phase correcting needs without using any pedal board real-estate. 

Master Mute
Hit the mute pushbutton on The TX Underfacer to mute your signal before it reaches your amps. No matter what craziness is happening on your board, the master mute has the final say on what does or doesn’t get sent to your amp. 

You can also control the master mute with RMT remotely on top of your pedal board. 

Summing
The TX Underfacer has two types of summing: Stereo Sum and Split Sum. To access these two modes, use the internal DIP switch to select which mode is best for you.

  1. Stereo Sum – This is the default mode The TX Underfacer ships with.  In this mode use stereo effects as normal. When summed, the left and right inputs are merged and the exact same signal is sent to the left and right outputs.
  2. Split sum – Still use stereo effects as normal. When summed, the right input is ignored and the left input is split to both left and right outputs.

Ground Lift & Phase Correction

The TX Underfacer comes with ground lift and phase correction for players that want to run more than one amp.

  1. Ground Lift – There are times when two amps are being used that an audible hum/buzz can be heard coming out of your amps. When plugged into one amp only, the hum/buzz is not present.  This is commonly referred to as a ground loop.  This happens when there is more than one path to earth.  To safely fix this common problem, a transformer is needed to isolate your second amp and create one path to ground.  Push the red ground lift button to isolate your right amp from your left. 
  2. Phase Correction – Another common issue when running two amps is phase cancellation. Some amps are in phase in relation to each other and other amps are not.  When amps are out of phase with each other they are cancelling each other out.  This is most noticeable in the lower frequencies.  Normally this would mean you can’t use those amps together.  With the black phase correction button you can now put two amps that were out of phase, back in phase and working together.  To access this, turn on the transformer (red button) and flip the phase (black button).

Input
The TX Underfacer comes with a buffered input. This means before your guitar sees the first pedal on your board you are sending a high impedance signal to your pedals, preserving your tone. It also comes with an always-on tuner out.

 

IMPORTANT – Use only 9vDC centre negative plug to power! Current draw – 100mA
Dimensions including all jacks and push buttons are: 100mm long x 118mm wide x 34mm high.

    Cover too loose.
    Size: 300A Fuse Holder
    Nice looking, decent quality, versatile for different gauges. My only complaint with this holder is the cover doesn’t stay on very well, bought 3, and all 3 pop off easily, you will need to zip tie on.
