The Nano Q-Tron is a dynamic envelope filter that delivers the classic quack sound, funky sweeps, and vocal-like modulations of vintage auto-wah. The filter responds to your picking and opens or closes depending on how hard you play—ideal for funk, R&B, fusion, and groove-oriented styles. With Low Pass, Band Pass, and High Pass, you can choose exactly the desired timbre: warm and round, or distinctly vocal. The Drive control determines the sensitivity so the pedal responds perfectly to single-coils, humbuckers, or bass pickups. The Nano Q-Tron has fast tracking and a natural filter curve, giving clean and light overdrive parts extra expression.
