I was looking for a cheap and simple delay pedal and found the HB digital delay. It is very simple to use and has a nice decaying sound when the 'repeat' knob is turned up above 50%.
The features are lacking a bit. For example, the 'time' knob's range is not very large, and the lack of a tap tempo feature makes is hard to set precisely to the tempo of a song.
But if you are looking for a just a simple delay pedal for just small parts of a song this is a good, cheap solution.
