Ever been in the situation where you are absolutely certain that you've saved somewhere a while ago and now search you @ss off to find that file?

I just found the schematic for a DOD680 delay back. 2 weeks ago I spent some 2 hours attempting to find it....

So, since all of us save a local copy of every schematic we run into anyway..... better share it.... :D

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.

Thanks Dirk - it's in my archives now :wink:
By the way - those NE 570/571 compandors were a major part of the "analog delay" sound.
I have built analog style delays (BoSS DM2) with PT2399 digital chips, with and without a compandor and there is a noticeable difference in the sound.
They are an interesting device when overdriven too :wink:
Cheers
Steve
