Ernie Ball‘s Expression series takes the wah/volume pedal chassis concept and applies it to other effect types, therefore allowing a sweepable foot control for some paramters.
The Ambient Delay has standard knobs to control the feedback, delay time, and reverb level, but the foot sweep provides a throttle control for the amount of ‘mix” of ambient texture in the overall sound. The effect is actually a combination of delay and plate reverb, so any fluctuation in the sweep also adds and subtracts how much reverb comes across in the tone. The effect also has a connection to add an external tap tempo controller.
Here are some videos of the Ernie Ball Ambient Delay.
The Expression Series Ambient Delay provides a hybrid of digital delay layered with plate reverb, for everything from slap-back to extended repeats. It features settings for delay time (50ms – 1s), delay feedback, reverb level, and a foot-sweepable effect level control to create anything from subtle textures to ambient soundscapes, all without taking your hands off the guitar.
