The Big Zapper is a comprehensive take on our Green Zapper auto filter. It does everything the Green Zapper does with the Range and Sensitivity controls on the outside. It also includes a foot switch that toggles between the stock Green Zapper and a longer attack/decay. The Big Zapper goes beyond just being a tweakable envelope filter, though. It also includes a Clock Trigger setting for automatic filter sweeps at a wide range of speeds. There are two independent sets of controls and a foot switch that toggles between them for two dialed-in sounds on-the-fly.
