Up for sale is an Electro-Harmonix (EHX) Micro Q-Tron envelope filter pedal in Very Good condition. Kept in a smoke-free environment, this pedal shows light, normal cosmetic wear from standard pedalboard use. functions 100% flawlessly. All three pots (Drive, Q, Mode), the true-bypass footswitch, status LED, and input/output jacks are clean, tight, and crackle-free.


Why the Micro Q-Tron?

Packing the iconic analog Mu-Tron/Q-Tron filter voicing into a compact, pedalboard-friendly die-cast enclosure, the Micro Q-Tron reacts directly to your pick attack and volume dynamics. Whether you are dialing in liquid, vocal single-coil leads (think John Mayer’s "I Don't Trust Myself" or Jerry Garcia’s "Estimated Prophet" / "Shakedown Street") or snappy, percussive funk rhythm pockets, it delivers thick, organic analog sweep without hogging space on your board.

What’s Included:

 Electro-Harmonix Micro Q-Tron pedal


Not included

Box and 9v power cable


Key Features & Specs:

 100% Analog Signal Path: Warm, vocal, touch-sensitive envelope filter response.

 Drive Control: Sets the envelope sensitivity and filter sweep range to match single-coils, humbuckers, or active pickups.

 Q Control: Adjusts the peak bandwidth from smooth, subtle vowel shifts to sharp, resonant filter peaks.

 3 Selectable Filter Modes (Rotary Switch):

 LP (Low Pass): Emphasizes deep lows—classic, syrupy R&B, neo-soul, and funk warmth.

 BP (Band Pass): Focuses on the punchy midrange—ideal for vocal-like lead lines and cutting through a mix.

 HP (High Pass): Accents bright, glassy upper-register sweeps and crisp harmonics.

 True Bypass Switching: Preserves your core tone when disengaged.

 Compact Die-Cast Chassis: Standard Boss/MXR-sized footprint with a standard 9V DC center-negative barrel jack (unlike the oversized vintage Q-Tron enclosures that require 24V adapters).
