Electro-Harmonix Micro Q Tron Envelope Filter Pedal

Features: • True bypass • Drive control sets sensitivity and filter sweep range • Selectable low pass, band pass or high pass filters • Q control sets the filter's bandwidth from smooth to funky • Tough and compact die-cast chassis • 9-volt battery included Description: The Micro Q-Tron is a smooth envelope filter with a funky wah-wah tone. The filter is controlled by its internal envelope follower, analyzing the volume of your notes and the dynamics of your playing to directly sweep the filter's center or cutoff 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.
