Wilson Effects, Slapback Dual Delay pedal - Analog Voiced Dual Digital Delay. This pedal sounds fantastic! Two Delay settings available. I set one side as a Slapback, the other as a Light, slightly longer Delay. No menu, or holding down buttons, just 2 identical sides to set as you like (You can also run both Sides at once, each set differently for some pretty cool effects). Also has an oscillation button (I never used it). This pedal has a really nice sound. Just changed up the board ... Hate to see it go. It's a good one! Hand made in the U.S. (If you look at there homepage there is a way to route this to run Stereo). The newer version seems the same, but with a colored label. I like this metallic surface WAAAY better (pedal only).
