George Dennis Delay-Reverb pedal has been developed for crystal clear and studio quality sound. The unit has no noise and no hum. When the pedal is used in the mono mode, there is up to 2 seconds of delay available. When used in the stereo mode, there is up to 2x1 second of delay available. The pedal has a factory designed IC (integrated circuit) which will transfer the sound 1:1 without any change so that the instrument does not loose it's original sound. The battery strength is indicated by an LED Diode. When the diode starts blinking, the battery needs to be changed. Controls: Depth, Feedback, Fine time, Mode, Hold, Panorama, Stereo volume
