Nano Q-Tron

The Electro-Harmonix Nano Q-Tron is an envelope controlled filter effects pedal designed for tone-shaping through dynamic, responsive filtering. The pedal analyzes the input signal’s envelope and translates it to control the filter’s cutoff or center frequency, enabling a range of effects including auto-wah and dynamic filter sweeps. With roots in the classic envelope filter designs from the 1970s, the Nano Q-Tron features familiar controls for adjusting filter response and effect intensity. This pedal supports use with bass instruments. **Key Features:** - Envelope controlled filter effects pedal - Filter frequency responds to input signal dynamics - Adjustable filter mode and Q controls - True bypass switching - Compatible with bass instruments - Compact pedalboard-friendly design
