This is truely a weird one.
This can be a almost clean sounding delay if you want it to.
But you won't want it to!
You will want it to add some nasty distortion on your delays that get worse with any time!
Or turn up the "Coarse" pot and turn this into a weird noisemaker with the possibillity to still pass your clean signal.
Needless to say this weirdo PCB will let you build a clone of the Echobender by Caspar Electronics.
Oh yea and the layout is stupid!
Like REALLY stupid!
So if you don't at least have built a few things before this might not be a good one to start.
To everyone else:
Go ahead and torture the hell out of a Pt2399 chip!
