Sili face ... sort of :)

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 
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

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

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?
