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.

QUICK SPECS:

- 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

- Comes equipped with a 9Volt battery and can also be powered by an optional 9Volt power supply
