There are a selection of instant go to delays available in the market today but if you choose to be a little more creative there is the iZotope Dynamic Delay plugin better known as the DDLY.
iZotope DDLY combines two delay lines split from top and bottom giving you an opportunity to be creative with your mix. You can also add character to a drum loop or your vocals by adding rhythmic complexity to your mix.
Having two split lines of delay allows you to send different signals thru these lines, one can be louder than the other providing a clearer sound.
