Single op-amp in DIP-8 package. Best known as the IC used in the Proco RAT since the mid-2000s, replacing the discontinued LM308. The datasheet specs are almost exactly the same as the LM308. The main difference is that the OP07 is internally compensated, so it does not need the 30pF capacitor between pins 1 and 8.
JHS has a great RAT article that includes a myth-busting section about the LM308 vs. OP07, measuring frequency responses to prove that the two chips do in fact sound identical in the RAT circuit.
