iTunes: Dubstation 2 - Audio Damage, Inc.

Easy to use and understand, Dubstation works just like a hardware delay pedal. True stereo operation and a nice saturated feedback path provide an instant-classic delay effect that has been used in thousands of commercial tracks.
Features
>> Tempo-synchronized or millisecond timing.
>> True stereo dual time mode, single time mode, or ping-pong.
>> EQ and saturation control on the feedback path, for tonal control.
>> LFO to delay time, for chorus and tape effects.
>> Tempo-synced stereo looping ("infinite mode") with sound-on-sound and reverse.
>> Heavily optimized for extremely low CPU usage. Use as many as you want, even on an older device.
