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.

Controls
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 – 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 9V 100mA 1/8" tip positive adapter. 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.

This thing sounds great. I love it for stuff that sounds like RHCP, basically. However.. not sure this is built very well since in the first 3 weeks it went straight to Bypass and right as that happened, my cord from the bass to the pedal stopped working.

Want to sound like Jerry Garcia?

Easy to use, plug in and play. Capture the sound sound of Garcia's Fire on the Mountain and Estimated Prophit from Cornell University May 1977. I have read reviews of this unit not living up to other envelope filters, like EMMA and others - I have never played them, but this filter does the trick. Easy to use, and it gives you the best bang for the buck. Buy this and you won't be dissappointed!

This Pedal is great. It's the best sounding Envelope filter I have ever used.

Compared to other filters I have used, you get that Funky swirl of tonal spice as soon as you step on it. Easy to dial in sweet tones.

The only thing I dont like is the price of this pedal). But I think its deffinatley worth it!

such a great pedal

Reviewer's Play Style: everything really
I bought this pedal on a whim when I was buying another pedal, I knew it gave you a funky sound and that people liked it. So i bought it, plugged it in and wow, I immediately was impressed, didn't even start playing with knobs at that point, sounded so good, and once you get a feel for the knobs (which doesn't take long) you can have some serious fun, it works reallllly well on single notes opposed to chords.
