The Electro-Harmonix Knockout Pedal -Works great and is in excellent condition, in the original box with two patch cables shown. Velcro on back.

This gave my flute tone the heavyweight punch it needed. I used this with a microphone at my flute after the eventide mixer and it evened everything out for the remainder pedal effects. I switched to iPad/loppypro for my pedal rig so no longer in need of these pedals.

Everything else is also for sale including the Boss rig pedal board/cables. Update: Eventide and Ditto X2 are sold.

Two powerful filters are the key apparently they made everything rich in sound.
