The Animals Pedal Double Spy Mission is Impossible Filter is designed to make the difficult-to-configure envelope filter/auto-wah easy to use. Adjust the RANGE knob to match your guitar or bass, and control the tone with the FILTER knob. You can basically create your sound with just these two controls. The MODE switch changes the direction of the filter. Up is up, and down is down. This item is an outlet item from Lep, but it is new and unused (not covered by warranty).
