Reply to Delay Pedals

Anyone else on here DJ with outboard effects? I know traktor and serato have those built in but I still like to rock a delay pedal sometimes to get better dub trails. I decided to break down using each of the stereo delays we carry at the store I work at in an article for our blog. Those interested check it out. Any input appreciated.

Interesting side topic, are outboard effects units obsolete now with effects built in to software that can be controlled via controller soundcards? I know a few dudes who still love their Pinoeer EFX's.
