I wouldn't even understand how the 4096s are "disengaged" for flanger only operation by 6:15 tomorrow!

Does anyone have a clue?

It's a little odd that one of the 4096s is on a "daughter" board. I wonder if it is in series with the board mounted 4096 to double the delay time.  ???
I just designed a new fuzz circuit! It almost sounds a little different than the last fifty fuzz circuits I designed! ;)

the mode switch. upper right corner of the schematic.
That's where it's at.

Hey Dave,

I saw S1A but it just switches the LEDs.

There is an arrow at the confluence of S1A and D6 that says "To Effect Switch A."

Where is effect switch A?
I also don't see any separation (means to bypass the 4096) between the 512 and the 4096.

I see it now....S1B bypasses the 4096.

Okay...

If you look in the upper right corner, between the output of U3 and C32/S1B, you'll see a box that's labeled EM450.

Below the box it says, "optional"

I'm sure that the 4096 daughter board is just a "copy" of the board mount 4096 circuit used in series for additional delay time.

Stephen,

The link that you provided deals mainly with the loft 440 but....I did recognize a posters name from another forum...Pro Audio Design.
John Roberts mentions having something to do with the design of the 440.
