Boss DD-200 Digital Delay

Okay, disclaimer, I knew upfront it has no reverb, so I opted for another more expensive Boss. Anyway, yes this 200 has tons of params & values to choose from. I use a delay for both my electro acoustic noise box and waterphone, each at one of the stereo channels. If it were only for the delay, I would have kept this 200, but because I wanted to blend in a reverb, which I knew this 200 hasn't, I decided to go for its bigger brother. The 200 quality is excellent. No hiss nor noise or hum, just pure. The only thing that I could not find in this 200 is what I would call a "fade-out", to make a repeated delay fading out gently rater than an abrupt ending.
