Interesting Delay
Try this when your looking for something interesting in the EFX department and struggling for ideas.
When you want to add some delay, mess around with the feedback, it will create some interesting effects other than the standard presets. Features to tweak while messing with the feedback are the Low and High-Cut controls. Using these filtering controls can make the delay darker (using High-Cut), thinner (using Low-Cut) or narrower (using a combination of both filters).
