Electro Harmonix Micro Q-Tron

The Electro Harmonix Micro Q-Tron is a versatile guitar effect pedal with a smooth envelope filter and a funky wah-wah tone. Controlled by its internal envelope follower, it analyzes the volume of your notes and the dynamics of your playing to directly sweep the filter's center or cut-off frequency. A stronger attack or louder note will produce a wider frequency sweep while softer playing produces more subtle effects. Use the Q control to make the effect more dramatic
