First, I like to apologize for writing this thread for help on what errors i'm doing or why isn't it working. quite a shame on me for a stompbox freak.
even though there is another significant thread that was posted, unlike me, i'm the impatient type and in need for guidance for this project i'm doing.

anyway I started, and apparently ended, on breadboarding a silicon fuzz face from the following website:
https://www.smallbearelec.com/HowTos/BreadboardSiFF/BreadboardSiFF.htm

as it turn out, it did not work as I plug in the amp, literally nothing is heard as I plug it. (yes I plug the battery and nothing work, even though its not pictured.)
I've wired and corrected all the values pinned of the board and check every layout connected to the board correctly shown on the website.
My main concern could be the issue of the mono and stereo jack wiring or done wrong. (check last two pictures?
the least I thought, and just don't want to think of the imaginable, was they aren't connected thoroughly.
seek pictures for in depth observation. even though its plain silly for me to do, its the least I can do for seeking help from you awesome folks. thanks a zillion light years!
(hint: right click the image into a new window or tab for better results or drag it into another view! :o)

it looks like Q1E is going to + instead of - (ground)


remember, the debug thread...voltages will help
always think outside the box

looks like the hots and grounds are touching at the jacks? could be a photo illusion?
my life is a tribute to the the great men and women who held this country together when the world was in trouble. my debt cannot be repaid, but i will do my best.

hi again lucifier

i've connected the jumper from Q1 emitter to the negative ground, yet nothings coming to life. 
is my C2 capacitor (B16 - B21) right? it should've look more like C1 but instead its a brown circle bead one. (221)
hows my stereo and mono jack soldering work and its input?

I just didn't want to think the possibilities have failed on my project  :icon_sad:

your 221 is a 220pf..(which is going to 9v+ btw ;)).it should be a 22uf electrolytic,the same ''type'' as your input 2.2uf to ground..

like joe said its hard to tell if your jack is wired weird!!!!....

anyway i felt kind today while i was having breakfast, so i knocked this up for ya...... here is how i would put it on breadboard....with the right 22uf cap ok.... ;)

check your stereo jack...make sure you have sleeve-ground....tip- in.....have fun!. :icon_cool:

voltages...it's all about the voltages...double check everything with deadastro's breadboard and then pull out your multimeter (hope you have one. it's necessary if you'd like to continue building & troubleshooting)

does connecting the wiper of the volume pot to the tip of the jack really work? in my case, it doesn't work.

But before that, I was working on the smallbearelec.com figures. I connect the 22uf as well.
I finally found out that I have to connect the sleeve of both jacks to the ground (duh! or i should've known by myself, thanks to you guys).
Apparently it doesn't functionally works fully, I like to say around 65% working i guess.
It connects, but it only works when i strum my guitar loudly, more likely to work on playing on the low e strings.
they say it could be bad connections to the board, I was kinda concern with the jumpers since they are basic lead for soldering.
any suggestions on fully operational worked stompbox on breadboard?
I'd like to continue on figuring to apply a feedback control for oscillations effect, which I have no clue what to do on
