IC underneath the electrolytic is a TL072CN, and the IC underneath the film cap is marker'd out.
I love that he marked that out :applause:

It's a 386. I was thinking of you guys when I did this! I never cross stuff out but when ever I do something like this as a joke to myself it ends up here! :D

that a trimmer going to the input of the 386? I've built a PPirate before and found I got some clipping if I dug into my guitar, does the trimmer help with that?

It's a trimmer.
These have low headroom, it's intentional!!!
That's why I black out ICs. Protect my mojo secrets.

Could someone post a verified schematic for the Deluxe version, please?

I'll draw a vero layout...

Here is a vero layout that works well for me. It's from the Madbean schematic so it's not the deluxe version but it does sound just like the original You Tube demos. I'm not sure of the correct taper for the pots but log for the depth pot and linear for the others seems to work well. I tried a few LDR's and they all worked to some extent. However I got some great results with the Silonex NSL 4962 (available for Farnell amongst other places). I should say that I copied this layout from a paper version (I'm new to DIYLC) so it has not been directly verified (although I have checked it over a few times.......).

I didn't build one using this layout but I did build others using FXgod's layout in previous pages as well as just doing a perf build. I used the linked below photocell and a 5mm waterclear White LED.

I don't know about vactrols (I didn't try one) but you can get a very strong effect if you are prepared to mess around with the ldr/led. I originally used a bright white led but the effect was actually too bonkers for me so I swapped it for a bright blue and this was more controllable. As I understand it, the spectral peak of the ldr (CdS) should be about 520 nm (should be bang on for bright green) but I read somewhere that this can vary by +/- 50 nm, hence the need to play around with the led.

I took the vactrol out and messed around with the led/ldr and Im happy with it now. Id call that layout verified but it looks like it could be shaved down a bit. Maybe I'll have a crack at it and post my layout this weekend.

well, here are my files for this circuit, in the rar you can find schematic, layout and pcb in pdf format ready to etch. Also have the eagle files to modify something if you want.

Don't really know how you all go about solving pedals, but all I've ID'd so far is the ICs and caps (5-47uf, 8-0.1uf, 1-.01uf, 1-1uf, and 2-.001uf). I'll keep trying to make out all the components, if anybody cares.
hi friend.
have you got the pot values of the deluxe version, i would make a clon.
cheers

Check your regulator pinout - You might have it reversed,
