From the manufacturer
Micro Q-Tron Envelope Filter
The Micro Q-Tron is a smooth envelope filter with a funky wah-wah tone. The filter is controlled by its internal envelope follower, analyzing the volume of your notes and the dynamics of your playing to directly sweep the filter's center or cutoff frequency. A stronger attack or louder note will produce a wider frequency sweep while softer playing produces more subtle effects. Use the Q control to make the effect more dramatic.

MODE SwitchDetermines what frequency range the filter will pass. Emphasizes lows in LP mode (Low Pass), midrange in BP mode (Band Pass) and highs in HP mode (High Pass). |
Q CONTROL KnobDetermines the peak bandwidth of the filter. As the Q control is turned clockwise, the filter will sound increasingly narrow with a more obvious peak, making the effect more dramatic. Start with Q set to about 2 o’clock. |
DRIVE KnobThis is the filter sweep sensitivity control. Turning the DRIVE control clockwise will cause the filter to react more to your playing. The more you turn up the DRIVE control, the higher in frequency the filter will jump when you play a note. When first plugging into the Micro Q-Tron, start with this control at 12 o’clock. |

There was a problem filtering reviews right now. Please try again later.
The outer case is strong and the pedal feels solid, but after just four months the pedal died on me. It just stopped working. I've got a board full of pedals, many of which I bought used and have for years and even decades, and they've all held steady. I expected better reliability from EH.

EHX hat einen super Klon von Mutron kreiert. Wenn man sich ein paar Minuten mit der diffizilen Einstellung des Drive Potis genommen hat, kommt bei dem Teil nur Freude auf.
Je nach Eingangssignalstärke (Gitarrentyp ) sollte der Driveregler angepasst werden. Dann hat man ein fantastisches Guitarpedal, welches anschlagdynamisch einen einzigartigen Modulationseffekt ausführt. Nicht mit Autowah verwechseln! Autowah hat keine Anschlgsdynamik, sondern arbeitet nur auf Zeitbasis .
Seul bémol, il y a une augmentation conséquente du volume lorsqu'on l'enclenche, c'est assez génant ! dommage qu'il n'y ai pas de réglage de volume ..
