Rodentia

I have been working on three Proco Rat pedals for a client. Also did some breadboarding. I have observed that the tone of a Rat is strongly dependent on the particular LM308 installed. These are all legit parts, but there is enough part-to-part variation to make a noticeable difference. Has anyone else observed this?

Can't say I have tried enough back to back to notice. Think this more likely a variance in GBW from manufacturing altering the rolloff--
or drift/abuse over the years? I can only imagine that a lot of these chips have changed hands over a dozen times by now.
Or are we talking a mix of Moto, Harris and NatSemi?
