    A compact version of the classic Electro-Harmonix Micro Q-Tron envelope controlled filter pedal known for its organic, analog sound and expressivity.

    Envelope controlled filter is an effect type that ventures beyond the mainstream yet is equally at home in a wide range of genres and equally effective on guitar, bass, keys, horns and more. Electro-Harmonix is a pioneer in this effect category and has been making envelope-controlled filter pedals since the 1970s! The Nano Q-Tron springboards off that deep heritage.

    Here’s how it works: The Nano Q-Tron responds to the user’s playing style and dynamics. The volume of the input signal it receives (also called the envelope) controls the cutoff or center frequency of a swept filter. This allows the Nano Q-Tron to create tone-altering effects ranging from subtle to dynamic, auto-wah to ultra-funky. It’s all about how you play and it’s super interactive.

    Electro Harmonix Nano Q-Tron Envelope Filter Pedal Features
    • Vol (Volume) knob which controls the pedal’s output volume
    • Drive Control adjusts its filter sweep sensitivity and how the pedal responds to the user’s playing dynamics
    • Q Control sets the peak bandwidth of the filter and determines how subtle or dramatic the effect will be
    • LP BP HP Mode Switch controls what frequency range the filter will pass. LP (low pass) emphasizes the lows, BP (band pass) the midrange and HP (high pass) the highs
    • Pedalboard friendly, compact, rugged enclosure
    • True Bypass switching
    • Comes equipped with a 9Volt battery and can also be powered by an optional 9Volt power supply

    Awesome pedal. Awesome pedalboard footprint.

    Awesome pedal. Awesome pedalboard footprint. Looks great and sounds great. I dig it. As someone who isn't coordinated enough to sing, play and utilize a wah pedal, this is perfect.

    Grateful to have this pedal

    One of my favorite effects, aside from having a wah, is having an envelope filter. I had always wanted a Q Tron and finally acquired one. I have to say that these pedals are a lot of fun and will aid in your creative ideas and ability to express yourself in a whole new way—a must-have for me. The Na...

    Feature rich pedal to get your 70's vibe on!

    I have always had good experiences with EHX products and decided that I would give this version of the Q-Tron a shot. I love the sounds Warren Haynes get's from his Emma Discumbobulater envelope filter, but did not want to pay the hefty price tag for one. I've been using this pedal about a month now...

    I like the smaller footprint

    I have an older big box Q-Tron from way back. I really like that model but wanted a smaller footprint for another pedalboard. This fits the bill (board) perfectly and the addition of a volume knob is incredibly useful.

    It does that thing!

    I was looking for a funk, rhcp, knopfler thing. It does it in spades! The only issue I have with the Q Tron is I find anything above or below midway on the 3 settings seems to be useless for everything short of just experimenting. Still, this pedal looks cool and sounds cool.
