Tonex One is the latest addition to IK Multimedia's Tonex series. The pedal has a mono input and a stereo output on a TRS jack. The latter can be used as a stereo output, a dual mono output or a headphone output. The Tonex One has 4 potentiometers with the following functions: 
 
Gate / Bass: adjusts bass and noise gate threshold
Comp /Middle: adjusts the midrange and compression ratio
Reverb / Treble: adjusts the treble and the reverb mix
Volume / Gain: adjusts the saturation level and volume of the amp
 
The second knob functions are accessed by pressing the ALT button. The pedal has 2 operating modes: Stomp (ON/OFF) or Dual Preset. In Dual Preset mode, the foot switch toggles between 2 presets. 
 
The Tonex One has a USB-C port so it can be used as an audio interface, allowing you to connect monitoring speakers directly to the pedal's stereo output. The colour of the LEDs can be customised so that several Tonex One units can be used at the same time. 
You can store up to 20 presets in the pedal, drawn from the 200 Premium Tone Models included. Of course, you can also browse the ToneNET to take advantage of the 22,000 free Tone Models and integrate them into the pedal.
