The 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 (bandpass) 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
