Solved. See photo from another pedal for comparison. It's a TLC2262 dual opamp from Ti. Makes sense, EHX has been using TCL226x in another designs as well,...

Thanks guys, I've photographed and identified the other chips as best I can. U1, U2, and U5 are RC4558. U6 is LM393. Lettering on U7 doesn't appear to match...

The title says it all - U7 blew up in my EHX Nano Metal Muff and I'm trying to ID this part. If anyone has one of these pedals they can crack open and let...

So I really screwed up. Got a nonworking EarthQuakerDevices Sea Machine v2 in great shape cheap because it didn't work. I confirmed when I received it that...

Fixed! First diode in the tripler (D16 on the schematic) tested infinite in both directions on my DMM. Replaced it and channel switching came back immediately....

Thanks for the suggestions. The 4070 tests ok. Looks like the problem is in the +12v power supply. It's a voltage tripler on the 5v AC secondary of the power...
