MORE Uglyface questions...

[$uperpuma]

OK...Uglyface built and sounding pretty darn good...but I was wainting to make sure that some of the things I'm hearing are things that should be there... when testing the uF outsde of an enclosure I had great sounds and sensitivity...when I put it in a box, Istarted to get a stray crackle...now I know that when the threshold is in the "in between point" just befor full oscillation, there will be some carckling..but with this one, if I have the tone knob on the guitar all the way up, the crackle never goes away.  If i turn the tone knob all the way down, I have to most predictable, pleasant results with the effect all together... Any insught on eliminating this crackle?

Oh, and on the "oscillation during bypass queastion... if there is a way to connect lug 1? of the threshold pot (pin 7 of the 386)  to ground upon bypass, it seems to eliminate the oscillation.

Thanks

RunoffGroove suggests adding a .001 cap on the output to tame the highs.

I believe you get crackle with the 'threshold' at 8 to 9o,clock position ?
I was not able to get rid of it as well .... learned to live with it...
Btw ...built the Q&A VCF after with switchable and an expression pedal option which makes it into a freaky synth wah...
With the UF+VCF, my pedal board becomes sort of analog synth as it goes through delay , phase , ps3 , chorus ..tremolo......
you can sit down and tweak the whole day... drives my dog crazy

this pedal is wicked ...even the paintwork cracked...

Crazy! Is that two Ugly Faces in parrallel?

Nope its Tim's Q&D VCF and the Ugly face.

Cool, I did that as well but I used an LFO to control the VCF instead of an expression pedal. I also hooked up the LFO to control the uglyface's frequency via the LED/LDR combo.
A thingmod after an uglyface is pretty good as well.

How do you go about using an expression pedal to control the frequency of the UF? I think I still have some room in my enclosure...
