The used Electro-Harmonix Q-Tron Nano Envelope Filter pedal delivers rich, funky auto-wah tones in a compact, pedalboard-friendly chassis. In great condition and fully functional, this analog effect pedal features a simple control layout with Drive, Q, and Mode controls, allowing you to easily shape your sound. The Q-Tron Nano responds dynamically to your picking attack, producing expressive and sweeping filter effects ideal for funk, rock, and jam styles. True bypass switching ensures your tone remains unaffected when the pedal is off. Powered by a standard 9V power supply (not included) or 9V battery, it's perfect for guitarists or bassists seeking that signature envelope filter sound in a rugged, space-saving design.
