EBS

The EBS BassIQ is an analog envelope filter pedal that is triggered by the notes you play. The results are the funkiest and most responsive sounds in a stomp box.
Auto-Wah or Funkadelic Sounds
The pedal achieves sounds ranging from the classic auto-wah to your own unique space-bass or Funkadelic sound. It features controls for threshold and attack, and runs in three different modes, Hi-Q, Up and Down. The 2008 edition uses true bypass technique.
