Excellent, glad to see it's verified. Maybe Aron can change the thread title?

Do you have a PCB for this, I'd really like to make this pedal

Layout: http://notinteractive.com/stuff/guitar/fx/uglyface-lfo-perfboard.png
DIY Layout Creator file (needs newest version): http://notinteractive.com/stuff/guitar/fx/uglyface-w-lfo.diy

I don't think the option for only showing traces works in the latest version, so you'll need to delete all the components to reveal the traces. Make sure there are pads underneath all the upright resistors before etching.

Thankyou so much Andrew, i really appreciate that.

Ronnie.

How do i open this file in DIY Layout Creator, whrn i clink the link, it looks like a bunch of html.

Thanks for your help.

Save the file to your computer, open DIYLC, File > Open, select the location you saved the file to.

I did that layout for perfboard construction, so as well as the missing pads under resistors, you might want to increase the thickness of traces where possible.

I clicked the link and saved the page to my desktop, i go to open it in the layout progran, and  it says invalid argument,

It doesn;t seem to reconize the file, sorry to keep bothering you with this, but do you have any idea'a on this.

Are you using the latest version?  - http://www.storm-software.co.yu/diylc/diylc_beta.zip
If you are, it might be that your web browser is changing the mime-type of the XML file when downloading. Internet Explorer has been known to do this in the past. Right-click the link to the .diy file and choose "Save As".

Thanks Andrew, i'll try those things,
Thanks for the link to the latest version , and for all your help.

Ronnie.

Hey Andrew, I couldn't get my version of DIY Layout Creator to open that file (I'm on a Mac) so I copied your layout to a PCB version. I kind of did this quickly so If anybody notices any problems let me know and I'll update it. The component names should match the ones listed in the link to the perf layout above. Also I didn't put offboard components but they will be the same as Andrew's perf layout. So here in one thread we have perf vero and pcb layouts for the UglyFace with LFO mods!!!








Thanks all!

Ian

Weird man, I'm on a Mac too  ???  Thanks for doing a PCB, but there's no need to credit me as all I did was add Mick's mods to Gary Burchett's layout (http://home-wrecker.com/uglyface.html)
I'll have to check that my server it delivering that file with the correct mime-type.

The above PCB layout is now VERIFIED. Just plugged it in and it worked first time.

The LFO is great although I don't hear much of a difference in the ramp up/down switch. I wonder if using germanium diodes would make it more pronounced because of their lower forward voltage?? Also, I saw it mentioned somewhere, but a reverse audio pot would be a significant improvement for the LFO speed knob. As it is most of the usable range is in the last 10%.

Also, this is the first time I've tried an UglyFace with the cap on the input to ground. Definitely a warmer sound, I might remove it or at least put it on a switch considering usually the point of an UglyFace is total sonic destruction.

I plan on trying the blend mod next. I'll post back here if anyone is interested.

Finally, I used a 100k frequency pot this time as opposed to the 250k recommend at the home wrecker site. I'm definitely going to swap that for a 250k. This allows the filter sweep to get down real low.

Hi! A fuzz with an enveloppe and a lfo...i think!

http://www.diystompboxes.com/smfforum/index.php?topic=66861.20

Maybe you can reach that kind of effects...

Here's more sound samples of the Uglyface, Tremulus Lune plus an envelope filter tacked on the end. Gotta build one of these!  http://ca.youtube.com/watch?v=2W4dKSmPkL0&feature=related

Thank you very much for the PCB, Ian,
I'm gonna etch it this weekend and start building it.

You have Volume 3 on the vero...then under the notes you have Volume 3 to ground. I think you mean Volume 1 to ground.

oups  :icon_redface:

you're right, i'll correct it soonish...

Thanks!

btw any chance of getting a full schematic up? I know when I build this it will be a total pain to debug (if I have to) without a schematic.

What is the point of the trim pot? How should it be set?

Hey, First post  ;D. :o This is really cool! I'm thinking of doing something similar with an overdrive design I'm working on with lfos for the tone and gain (I want it to sound really hellish then have the distortion fade in and out). Couldn't you just use an H11F3 or similar as a variable resistor instead of that vactrol? Looking at the data sheet ( http://www.fairchildsemi.com/ds/H1/H11F2M.pdf ), the anode is pin 1, the cathode is pin 2, and pins 4 and 6 would be your resistance. So it would be a pretty easy modification. I think there would have to be a resistor before pin 1 but I'm not sure what the value would be?

R10 is supposed to be a 1K or 2K trimpot.

I see what you're saying now. I didn't even notice at first that this was suggested to be a trim pot. I don't know for sure what this does but I'm going to take a guess.

I'm wondering if it is to control the volume of the LFO. The reason I think that is because when I did my build I used a 1K fixed resistor and my LFO is noticeably louder than when off. I might have to open mine up and see if this is the case.
