Teeny package, big effects!

The Electro-Harmonix Micro Q-Tron Envelope Follower Effects Pedal is everything you love about the Mini Q-Tron, in an even smaller, rounded-corner die-cast case! The Micro Q-Tron is a unique type of sound modifier, in which the user's playing style controls the effect. The volume of the input signal (also called the envelope) controls the cutoff frequency of a swept filter. As the volume increases or decreases, so does the pitch of the filter.

Drive Control - The filter sweep sensitivity control. Determines the width of the filter's sweep range by the input signal. Produces more sweep when it's turned clockwise.

Q Control &ndash Determines the frequency peak of the filter. Creates a more dramatic effect when turned clockwise.
Mode Switch (LP, BP, HP)-Determines what frequency range the filter will pass through. Emphasizes lows in LP (Low Pass), midrange in BP (Band Pass), and highs in HP (High Pass).

Footswitch - Engages and disengages the effect.

Connections - Connect your instrument to the Input jack and your amplifier to the Output jack.

Power - The Micro Q-Tron is powered by either a 9V battery or an optional Electro-Harmonix US96DC-200BI 9VDC Guitar Effects Power Supply. Inserting a cable into the Input jack engages the battery. For longer battery life disconnect the input cable when not in use.

Playing The Micro Q-Tron
The Micro Q-Tron's effect is controlled by the user's playing dynamics - a stronger attack will yield a more dramatic effect, while softer playing will produce more subtle effects. Use the full range of control settings in combination with different playing techniques to obtain a number of different and unique effects combinations.

  • just what i was looking for!

    As reviewed by mike on 4/29/2010

    Watery floppy funky goodness. This pedal is awesome, gives you a variety of frequency options to get just the tone you're looking for. Sounds awesome on bass too. Sturdy, super affordable, killer graphics, and sounds f-ing amazing. GET IT!

  • Works ok for a while!

    As reviewed by Tommy Gabele on 11/23/2010

    First off the pedals are cheap and made in China! I bought my Micro Q-tron pedal about 3 months ago, I still have the receipt and original box. I also sent in the little warranty card with my stamp! 2 days ago my pedal stopped working and I called them up. They told me to send it back in with a check for $13 and they would repair it. I told them it was under warranty still. They said that check would cover shipping and handling to get it back to me. RU Serious I just bought this thing! Now I got a go stand in line at the post office and mail back and pay money! I told then never mind I am just gonna throw it in the trash and not buy any more pedals from them. I could not run my shop like that! I would never treat my customers like that! I would rather stay at work make enough money to buy a Mutron-lll and have a quality product from 30 years ago!
