Another easy option:
Using a cross fade, send the dry to and wet delay sound into it to mix in wet delay.
Use 1 Gaffa delay with 100wet no dry.
Place a clean delay with 100%wet and 0%feedback, just on the left side straight out of gaffa (or right doesn’t matter) with a small delay time so it’s always just a small amount behind the other side - it makes for an amazing stereo image.
You can set up another line select switch to bypass everything with 1 foot switch, or assign the gaffa and extra left side delay to a CV button and have both turn on and off.
Make sense?
When sharing is available again I can demonstrate with a patch.
