This maybe a dumb question Where is the serial number located on the Little Phatty (Stage II) ?
On the Stage l it’s located on the back. I’m not sure where it’s located on the Stage ll..
Look for a really small metallic sticker on the back. 
I had trouble finding mine at first, too. 
It isn’t that small is it? 
Not really, but I was expecting it to be somewhat noticeable. It’s not. It’s on the left-hand side, opposite the side with the power switch and inputs.
Maskin, I am used to such numbers being on the bottom or on or near the warning sticker, so when it wasn’t on either of those places, I looked to the left and hit my forehead with my hand.
It’s written on my boxes too so there is no way to miss it.
Wasn’t on my box…I looked for it there first. 
Hypemaster_herb, did you find it?
Thanks for the replies.
I still haven’t found the serial. I even checked the box.
Heres a pic of the back of my LP. I don’t see anything on the left side.
Left if you stand in front of it…so right from the back… 
Btw…what is that metallic sticker doing there…
Last time I checked …
“100-240 VAC
50 - 60 HZ”
Isn’t a serial number.
I guess it should be located on the left side from the back.. Seems like you don’t have a serial number.
Here’s the back of one of mine:
Thanks. This kinda sucks because, I got my little phatty during the promotion for the free CP-251 and I need the serial number of the LP for the paper work to get the CP.
That’s a bummer! I’m trying to think of other ways to find the serial number but I can’t come up with something..
I believe the date of purchase on the receipt is the most important part for the CP-251 deal. The Serial # is perhaps needed to avoid sending multiples (NO, NOT MULTIPEDALS). Contact Moog and they should be able to square things away and send you that missing #/sticker (is so desired).
