Digitech PDS mod--Is there a pedal that does this?

[<hqr@earthlink.net>]

Hi--
Today I got a strange bird out of storage--it's a Digitech 2 second delay
mounted on an old Morley pedal I had made for me back in the 80's . . .
Here's what it does--
There are three knobs on the side which control feedback, delay volume and
delay time--the pedal can be switched to control either feedback or delay
time.  Changing delay time also changes pitch on this puppy.
Is there a commercially produced pedal that does this?  I managed to get
this unit to function, but it definitely needs some tuner cleaner and
general attention--thought I'd share . . .
