Here's a simple version just using the delay block in the dual mode and a bit of the options available in the block.
IMO you can get a pretty useable sound with very little very effort.
Sorry for the long recording, I got a bit carried away...

The "Mono Tape" delay type in the Axe-Fx II is far more realistic than the one in the DD-20. So why copy the DD-20 ...
Note that the "Stereo Tape" differs from the "Mono Tape" in more aspects than just mono/stereo.
