It's the "Built-in Guitar Distortion Active Overdrive Circuit F03" from Guitarfetish.

Lots of marketing drivel mixed in there, but it does look to be a tight little SMD board with a bunch of options...

  Looks like it has an opamp, I wonder if it's a buffered bypass output...

I bought one of these a few years back. It was alright sounding.
swaped it in place of one of my tone pots. Have to find room to jam a battery in
the cavity. Remember to unplug your cable or the battery wont last long
Now its sitting in an enclosure unused on my shelf till the day arrives i want to give it
another go.

They also sell an onboard Analog delay board:

Looks pretty cool for $50!

Says it has a range of 10ms - 550ms... though, without spec'ing the bandwidth, any delay could be clocked to an infinitely long time.

I'm going to go ahead and bet that any 550msec SMD $50 dollar delay is not actually analog.

I was thinking the same thing... so we emailed the company to ask about it. I was guessing that it was like the PT80, analog front end/back end on a digital chip. To my surprise, the answer from Guitar Fetish was:

"yeah it's old school- Modified bucket brigade- PURE analog- Chips are made for us by Hyundai in Korea- proprietary"

For $50, we're thinking of getting one here to try out...

I can't comment specifically on that product, but I have thier pickups in a couple of my guitars and also have thier "clapton" mid-boost circut in my strat, and I am happy with thier quality and the customer service they provide.

just viddys like and opamp with clipping diodes (pair of 4148s) and switchable gain, or just a gain pot (i can really tell if its a rotary switch or a regular pot)
the ass load of resistors suggest thats it a rotary switch
id probably add a switch to cut the power to it and bypass aswell (3pdt toggle maybe? or with an led 4pdt??) so it doesnt suck the battery power
