So since a friend of mine borrowed my bass-heavy fuzz face and will not return it for couple of weeks, and i do need a fuzz for rehearsals and gigs I ve made one using Sili Face schematics http://www.home-wrecker.com/sili-face.html
It was kinda noisy so i ve replace that 4k7 with 1k, instead of BC 549c's first one is BC 517 and the second is 2n2369A. I ve used a 500k pot. Also a diode clipping in series with a switch on one side an orange led and a germanium diode ( love this combination ) and on the other blue led and some unknown russian diode ( measured around 0.6 ). I wasn't happy with input/output caps combination, so i ve used a switch to chose between 10uf/1uf and 2.2uf/0.047uf . But i really can't tell the difference. Have i wired it wrong?

This was the only way to explain how i wired it, so ashamed of my lack of skill with paint :icon_redface:
It works nice as it is but i would love to have that option of switching caps.
excellent.
the output side of your switch diagram is hard to read, but i think i see were you are going with this.
looks wired ok, the values you have listed might be a little to hard hear any difference, depending on the hairiness of the fuzz. if you really want to doublecheck your wiring, sub a .005 in place of the 2.2 uf, and .005 on out. that should be quite audible.
Thanks you for advice, i will try it.
no problem :icon_wink:
hint for graphics: even for a primitive sketch in MS paint, you can select different colors for different wires, this would help the reader to understand. pretty sure most of us are using color monitors :icon_wink:

:) That was a quickie, hence one color. Next time I ll use multiple colors .
Changed to 0.005 and it was noticeable. So now i can switch between 10uf/1uf and 2.2uf/0.005uf. Its great, bass on 1 side treble on the other.
Here are the pics

So in theory i could use that kind of wiring ( but with multiple switches ) to control amount of bass in lets say Big Muff? On 1 side standard 1uf/1uf caps and on the other 10uf/10uf?
looks cool!
yes, you can use this kind of switching for a muff and lot of other pedals.
Very cool. Thank you for your time and advices. :)
Is there a way put a led on a bass side?
