Electro Harmonix Nano Q-Tron Kitaraefekti

Envelope-Controlled Wah in a Pedalboard-Friendly Stompbox

The Electro-Harmonix Nano Q-Tron Envelope Filter packs the classic Micro Q-Tron sound into a compact, true-bypass pedal. The unit reads your playing dynamics and sweeps an analog filter, producing auto-wah and funky quack that react to pick attack. EHX has been making envelope-controlled filter pedals since the 1970s. The Nano Q-Tron suits guitarists and bassists who want a dynamic, hands-free wah.

What Sets This Pedal Apart

Unlike a standard wah, the filter cutoff is driven entirely by your playing dynamics. A dedicated Volume knob — absent on the original Micro Q-Tron — lets you match bypass level or boost the effect.

Three Filter Modes and Four Knobs

The Mode rotary switch selects between Low-Pass, Band-Pass and High-Pass responses. Drive sets envelope sensitivity gain, while Q adjusts peak bandwidth.

• Filter Modes: LP / BP / HP — Low-Pass, Band-Pass or High-Pass
• Drive: envelope sensitivity gain — controls how wide the filter sweeps with pick attack
• Q: peak bandwidth — subtle curve or sharp resonant peak

Standard Mono I/O and Battery-Friendly Power

A 6.3 mm jack input and output keep the pedal compatible with standard wiring. Running on a 9V battery (included) or an optional 9V DC adapter, it draws only 10 mA.

• Input: 6.3 mm jack (mono) — standard instrument-level input
• Output: 6.3 mm jack (mono) — feeds amp or next pedal in the chain
• Power: 9V battery (included) or 9V DC adapter — 10 mA draw

True Bypass and Pedalboard-Ready Construction

True-bypass switching keeps the dry signal completely unaffected when the effect is off. Built into a rugged die-cast enclosure, it's ready for daily gigging.

• Bypass: True Bypass — dry signal passes through untouched
• Dimensions: 114 x 70 x 53 mm — pedalboard-friendly footprint
• Package Contents: 9V battery and manual — ready to play out of the box
