Thaaat's the one! Indeed it is.
I couldn't recall which circuit this was... I kept going back to the John Hollis Crash Sync, which is close, but not exactly the same.

Well, I'd sworn off building anymore Ugly Faces, but I'm gonna have to give this one a go.
The Crash Sync would be awesome to see in the shop, it's definitely different enough to warrant inclusion. At least so I can use up all these 555s I have

I'll have to look at the Ugly Face schematic, but at first glance I think it's a 1:1 clone.
It does use a ICM7555, the CMOS version of the 555 timer, however. The standard NE555 works as well, but the CMOS version behaves slightly different. It had me pulling my hair out trying to figure out why in the heck it wasn't behaving exactly like the original!
That said, I think I prefer it with the NE555 myself. It sounds a bit more interesting when the Threshold control is gating.

That's interesting, as I've tried the NE555 in the past and it didn't really do the ugly face thing. Will be cool to see how this schem compares to the others on the market, though.I'll have to look at the Ugly Face schematic, but at first glance I think it's a 1:1 clone.

Honestly kinda surprised it's taken this long for a full on clone to come out

This is cool.
Here is the original Ugly Face schematic from Tim Escobedo:
This is the one I made: https://dunningkrugerfx.com/toynbee
It's built on a board from Super-Freq
Adding some stuff for an expression pedal seems like a cool idea.

I've always wanted to build a Machette (Escobedo ugly face and bailey's LFO) from GCFX.

I just built one today according to the screen print, and it works flawlessly

To add after some tinkering- absolutely spring for the 9203 LDRs. I've been getting mine from Jameco. As for LEDs, the Tayda Superbright Red 5MM has the best response.
I'm thinking using pre-rolled vactrols and other LDRs has been why I haven't been enamored with every other Ugly Face I've built through the years

I didn't test every possible combo, but the 9203s and the Tayda Superbrights gave me the best range and response out of those I did try, and I like it enough that that's what I'll use for all future Ugly Face builds
