If you’re chasing Garcia-style auto-wah sounds but are overwhelmed by the full-sized Q-Tron+ pedal’s complex control layout, the Electro-Harmonix Nano Q-Tron offers the perfect compromise. Like its pedalboard-hogging predecessor, the Nano is an envelope follower that produces dynamic-controlled wah-wah sounds. The harder you pick, the wider the frequency sweep; the softer you pick, the more subtle the effect will be. Dialing in your sound is easy with the Nano Q-Tron — a few twists of its four knobs is all you need to unleash an avalanche of funk-infused, jam-band-ready quack. You also get true-bypass switching and a rugged die-cast chassis that’s compact enough for the smallest of pedalboards. EXH is a pioneer of envelope-controlled filter effects, and the Nano springboards off that deep legacy. Players searching for a top-shelf dynamic wah effect — in a pedalboard-friendly package — will find everything they need in the Nano Q-Tron.

Streamlined, 4-knob layout

The full-sized Q-Tron+ pedal is a lot to digest — it's a bit intimidating. That’s why Electro-Harmonix created the Nano Q-Tron. This compact stompbox is tailor-made for players who want to plug in and rip through a couple bars of “Estimated Prophet” without a ton of tweaking. The Nano Q-Tron includes a Volume knob to control your output, a Drive control that sets your sensitivity and filter sweep range, a Q control that sets the filter’s bandwidth from smooth to all-out funky, and selectable lowpass, band-pass, or highpass filters. At Music Experience, we’ve found that you can dial in this stompbox in a matter of minutes. The Nano Q-Tron is one of the easiest ways to achieve old-school auto-wah effects.

What Electro-Harmonix Says...

Envelope controlled filter is an effect type that ventures beyond the mainstream yet is equally at home in a wide range of genres and equally effective on guitar, bass, keys, horns and more. Electro-Harmonix is a pioneer in this effect category and has been making envelope controlled filter pedals since the 1970s! The Nano Q-Tron springboards off that deep heritage. Here’s how it works: The Nano Q-Tron responds to the user’s playing style and dynamics. The volume of the input signal it receives (also called the envelope) controls the cutoff or center frequency of a swept filter. This allows the Nano Q-Tron to create tone-altering effects ranging from subtle to dynamic, auto-wah to ultra-funky. It’s all about how you play and it’s super interactive.
