Micro Q-Tron

Analog envelope filter pedal that follows playing dynamics to sweep a low-pass, band-pass or high-pass filter for funky, wah-like tones. Suited to guitarists and bassists who want touch-responsive filtering in a compact, battery- or adapter-powered housing.

  • Analog envelope filter with internal envelope follower
  • Selectable low-pass, band-pass or high-pass modes
  • Q control sets filter bandwidth; Drive sets sensitivity and range
  • True bypass switching
  • Die-cast chassis, 4.75 x 4 x 2.25 in
  • 9V battery included; 15mA current draw

Cur síos

The Micro Q-Tron is an analog envelope filter. Its built-in envelope follower reads the volume and dynamics of each note and uses that to move the filter's centre or cutoff frequency. Harder attack or louder notes give a wider sweep, while softer playing gives a more subtle effect.

Three controls shape the sound. A rotary mode switch selects low-pass, band-pass or high-pass filtering. The Q control sets the peak bandwidth of the filter, from smooth to more pronounced and funky. The Drive control sets the sensitivity of the sweep and its range. A footswitch toggles between effect and true bypass.

The pedal is mono, with one input jack for the instrument and one output jack for the amplifier. It sits in a compact die-cast chassis and runs from an included 9V battery, or from an optional 9.6VDC 200mA adapter that is sold separately. Current draw is 15mA.
