EHX’s rich history was marked by many revolutionary pedals but one of our most distinctive lines was a group of analog drum synthesizers that included the Crash Pad. Like the original from 1980, the Crash Pad can create an array of drum sounds and other-worldly oscillation sweeps, as well as process external sounds thru its resonant filter. Plus, it’s been updated to respond to expression pedal/CV input for external control over the filter in real-time.
