Help - looking for a unique kind of effect

["David Kirkdorffer" <vze2ncsr@verizon.net>]

Hi - perhaps you guys can help me?? I'm looking for a delay footpedal that
can also bend pitch at the same time.  That is, as the slaps happen, their
picti is being altered up and down a little... as would happen with a
chorus.  I need at least 500ms of delay.

Any ideas??  Again, I nee this from a footpedal delay. I have this already
from some KORG rackmounts I have, but I'd love a smaller alternative than
carting around 20-year old rack effects. :-)

Many thanks!

David
