Maker: Electro-Harmonix

Model: Nano Q-Tron

Condition: New

 

Description:

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. 

  • 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

    It works! Quality pillow.
    Size: Standard (1 Count), Color: Original White (Cooling)
    This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.

    Most comfortable pillow I’ve ever slept on
    Size: Queen (1 Count), Color: Crescent White(cooling)
    This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.

    Smell
    Size: Queen (2 Count), Color: Original White (Cooling)
    The fact that there are not more comments on the smell of these pillows has me worried about some of yall. Listen, I LOVE the weight, and the firmness, it’s perfect for that. However, these pillows are RANK. They have a very strong mildew-ish smell that lingers. I took the outer cover off and washed it and let the pillow air out for a few days, the smell is still very strong when you press your face against it, which one does because it is in fact designed for that purpose. It smells so bad. It’s nauseating. I can smell it through two pillowcases and blanket that I threw on top of them hoping an extra layer would trap the smell. I’ll bake them in the Texas sun tomorrow and hope that helps, because otherwise these are the perfect pillows for someone who wants to feel like they are hugging a torso but can’t stand the sound/feel of someone else breathing. I don’t know…4 stars, if the smell goes away I’ll come back. Update: many many days later. Either they don’t really smell anymore or I got use to it. They’ve held their firmness and shape well. I like them.

    Actually Cooling Pillow
    Size: Queen (1 Count), Color: Original White (Cooling)
    This is a really nice pillow, I was worried it would be too soft or too firm but it's just right and it's actually cooling, it feels cool every time I touch it. I've noticed an improvement in sleep since using it. Would recommend!
