Trying to find a looper pedal

[H4T]

I've found a couple designs, but some have obsolete ICs. Are there any up to date looper schematics floating around out there? I've seen some loop A B boxes, but really all I need is a pedal that I can record riffs to and play them back live, like a one-man band kind of thing.
