Electro Harmonix Micro Q-Tron Envelope Follower Pedal

The Electro Harmonix Micro Q Tron Envelope filter is a big effect in a small package. The controls start with the mode, which are HP(high pass) BP (Band Pass) and LP (Low Pass). Next is the Q control, which determines the peak band of the filter. And the drive control sets the sweep Sensitivity. The EHX Micro Qtron also features:

• True bypass
• Q control sets the filter's bandwidth from smooth to funky
• Tough and compact die-cast chassis
• 9-volt battery included
• Optional 96DC-200BI power supply available
