      Electro-Harmonix XO Q-Tron Plus Envelope Filter Guitar Effects Pedal (150436)

Designed by Mike Beigel, inventor of the legendary Mu-Tron III envelope filter.

Electro-Harmonix' Q-Tron+ Envelope Filter pedal is the classic envelope follower with effects loop. Place your favorite effects between the preamp and filter section without changing the envelope drive. Be creative with the effects you plug into the FX loop and invent totally new sounds. Ratify your Mojo!

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

  • 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.

  • Funk!

    As reviewed by Josh on 4/13/2011

    The QTron+ is one of the most funky sounding pedals I've ever used. I bought it after researching many pedals to find something that provided the funky tone I wanted, and the QTron+ delivered. There is so much that can be done with this pedal so it is perfect for someone, like myself, who likes to explore tones and sounds. You really can't get bored of this pedal. It offers so much to the table and so much flexibility. The possibilities are endless. I suggest using this only with the tone of your guitar and amp to hear the full effect. I have used it with heavy distorion but generally i use it for clean riffs and solos.
