Since I won the TC Electronic Easter Egg Hunt, I have a Hall of Fame too now. But somehow I feel the Ghost Echo has a very distinct voice on it's own, so I currently have two reverbs on my board
For one, the Ghost Echo adds certain brightness to my sound, it makes the notes pop out more. And it's great before dirt, currently I have it before Mini and Elements. The greatness is probably connected to the brightness because even with dirt, it doesn't get that mushy, if anything, it makes it more aggressive and trashier. In front of the Mini, think Young Widows. And in front of the Elements, it creates this huge trashy wall of sound.
The pedal is not really versatile, but it does that one great thing. And that's just enough for me to still be excited about it even despite the super-versatile Hall of Fame sitting further down the chain.
