Have anyone built a 3207 based delay pedal?

[exztinct01]

I removed the circuit inside a Behringer CE300 Chorus Pedal and used the case for my MXR Distortion+ Clone. As for the circuit board, I didn't like the sound of the chorus so I desoldered the parts which I can still use.
I removed two V3207 delay IC and two V3102 Clock generator for the BBD. Question is, do you know of any DIY delay pedal that uses the 3207? I don't want these to be put to waste.

You could make a reasonable slapback echo with a 3207, but don't consider aiming for more than maybe 80msec delay.

The Maxon AD999 uses eight such chips. http://www.effectsdatabase.com/model/maxon/vintage/ad999
