Technical Specification

Electro-Harmonix XO Q-Tron Plus Envelope Filter Guitar Effects Pedal

  • Drive (Up/Down)
  • selects direction of filter sweep : upwards or downwards.
  • Norm/Boost
  • Normal mode allows setting the Gain control without changing the output volume.
  • Peak (Q on the Mini Q-Tron)
  • Determines frequency peak of filter. Makes more "effected sound" when turned up more.
  • Gain
  • Functions as both a volume control and a filter sensitivity control in boost mode. In normal mode it acts only as a filter sensitivity control, unlike the Mutron-III which also changes the unit's output volume.
  • Range (Hi/Lo)
  • Emphasizes vowel like sounds in low position, overtones in high position.
  • Mode (LP/BP/HP/Mix)
  • Select the filter used by the effect: Lowpass, Bandpass, Highpass or a mix of Bandpass with dry unprocessed sound.
  • Response (Slow/Fast)
  • Selects either a slow, smooth, vowel-like attack or the fast, snappy response of the original Q-Tron.
