Have scaled down photo sorry, think this is the BBD chip delay (i think thats what its called) Bucket Brigade Delay. There is a few different versions of this, the silver one with pots the black one with the faders which people go nuts for, there is a metal one with 4 faders by radio shack which is pretty much the same thing and i have another one by a company called Pyramid which is identical to the radio shack one. Its seems kinda like the same shit as mam and all the 303 clones, numerous versions by practically the same folk. I had too many of these i've been scaling down.
