The Ernie Ball Tap Tempo is a compact, passive utility pedal designed to provide external synchronization for time-based effects. It features a normally-open momentary footswitch, making it the primary companion for the Ernie Ball Expression Series Ambient Delay or any other effect unit requiring a standard non-latching trigger. Its simple, one-button design allows musicians to accurately set delay rates or modulation speeds with a few taps. Built with a rugged aluminum housing, it is engineered for heavy use while maintaining a minimal footprint on a pedalboard. Because the circuit is entirely passive, it requires no power to operate and ensures complete signal transparency.
