Delay circuits

[veracohr]

Does anyone know a good, easy way of making a delay circuit? Sometimes I stereofy mono synth sounds with a delay and pan the two, but that always gets done in the mix. I was hoping I could make a simple delay to be able to do this when I'm writing, and not buy a hardware effects unit.

Not sure the best way to go about this. I'm not up to designing an ADC to make a digital delay, but what about an analog delay? Does anyone know how to do this?
