It's an amazing effects unit quite unlike anything I own.
These are videos recorded on Instagram.
The sound is cleaner than my Buchla 288v ... though I like that for other reasons.
The WAD is so hard to find these days due to the rarity of its components.
.. those SAD1024 chips.
The SAD1024 is a 512 stage bucket brigade analog delay chip
It has 2 independent delay sections.
The Bucket Brigade consists of a series of capacitors that pass the analog signal
like a line of people carrying buckets of water to put out a fire.
The rate is determined by an external clock.
It's difficult to say what portion of the WAD's magic is due to the SAD1024 but for the record
these also use it:

Ebay has a few of these chips but who knows the quality. Or you could "borrow" them from existing pedals though I think that's sad (no pun intended).
An alternative chip could be the MN3007. Its also a bucket brigade IC.
It is used by Boss in the DM-1 & CE-2. Also in the EMX Memory Man & Small Clone
the AD-999 by Maxon & the Analog Delay by MXR.
