The EHX 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.

True bypass
Drive control sets sensitivity and filter sweep range
Selectable low pass, band pass or high pass filters
Q control sets the filter’s bandwidth from smooth to funky
Tough and compact die-cast chassis
9V battery included

Micro Q-Tron

With original late-70s Op-Amp Big Muffs selling for exorbitant prices, Mike Matthews decided to take the power to the people and reissue the classic pedal at a price that players could afford! The circuitry of the new EHX Op-Amp Big Muff Pi —sometimes also referred to as the IC or V4 Big Muff— has been faithfully re-created while several practical enhancements have been added including a compact, die-cast chassis and true bypass switching.

OP AMP BIG MUFF PI

Same design as the original EHX Q-Tron but with extremely useful Effects Loop and an Attack Response Switch. The Effects Loop gives the musician the ability to place an additional effect, or chain of effects between the EHX Q-Tron Plus’s preamp and filter section without changing the envelope drive. This is particularly important with most distortion devices, as most all do not have much of an amplitude envelope. The FX loop will also fire up your creative juices to try all sorts of combinations in the effects loop: try the Micro POG into a Deluxe Memory Man. You can invent all sorts of novel effects. The added Response Switch selects between a slow, smooth, vowel-like attack and the fast, snaked response of the original Q-Tron.

True bypass
Dedicated effects loop allows you to place any effect or pedal board into the loop
FX send and return without changing the envelope drive
Selectable low pass, band pass and high pass filters
Resonant peak control to adjust the filter’s Q from subtle to dramatic
Response switch changes the reaction time of envelope follower from fast to slow
Switchable hi or lo frequency sweep ranges
Adjustable gain knob and boost switch
Sweep direction switch for up or down filter sweeps
Power adapter included

We took the Big Muff Pi circuit and simply shrunk it without changing its rich, creamy, violin-like sustain and sound!

The EHX Nano Big Muff Pi works and sounds identical in every way to our classic NYC Big Muff Pi. Get a piece of the pi for yourself!

Crushing distortion
Singing sustain with attitude
Compact, rugged nano enclosure
True bypass
Adjustable tone
9V battery included
