Behringer VD400

Has anyone ever seen a schematic for the Behringer VD400 Vintage Delay?
I have one; its a great little Bucket Brigade delay pedal and silly cheap but I want to re-house it and change a few things about the way it operates.

For instance, one thing that bugs me is the way the foot switch kills the wet effect dead; If your playing a piece and you want to move smoothly from a section with delay into a section without, I'd prefer it if the delay petered out in its own time rather than abruptly stopping; is this normal behaviour with a delay pedal? this is the only one I've ever had.

So if anyone has a schem or knows where I can get one I'd apriciate a look at it.

Yes, it is perfectly normal.  Some more full-feaured delays have what is frequently referred to as a "trails" feature.  The input to the delay path is cut when you hit bypass, but whatever is in the delay path continues to be heard until it dies out.

Pedals that do not currently have that feature can be adapted to have it, but there are a few caveats.  First, you obviously need to have a schematic and sense of where the relevant parts and paths are.  Second, you have to forfeit your thirst for true bypass, since the feature demands that the delay circuit NOT be removed from the signal path.  So you better like the dry signal from your delay pedal, and whatever noise or other aspects it contributes to your non-effect sound, because it is always going to be there.
