Does it have a sticker on the bottom that says Vintage Rat? Might have peeled it off.

Vintage Rats were made between 91 - 05 so technically it could be an early 90's Vintage Rat. If the chip says OP07 on it, it's not a LM in there.

It's not to say that ProCo didn't use both chips in it through the years. I know they use the OP07 in the Rat2.

If you take the board out, you can probably see if it has been resoldered. The LM isn't internally compensated so they added the cap. The OP07 doesn't need the datinv because it's internally compensated. So if there isn't a spot for a cap dsting pins 1 and 8, the OP07 was probably in there to begin with.
