I found a stash of the original RAT Op-Amp chips (Motorola LM308N) chips at a nearby electronics depot here in the "Jerz" and started building these, no mods. If you want vintage RAT tone, we are here for you. I shot this out with my newer OP07 RAT in the video below, and though it's subtle, it does sound a bit smoother with richer harmonics, and a little less raspy with the filter rolled off (these are "cork sniffing" distinctions as you'll see from the newly uploaded shoot-out video). Board-friendly 125B enclosure.
