RM Axis Fuzz question about one resistor+one cap

[gigimarga]

Hello,

I've built a RM Axis Fuzz using this schematic: http://fuzzcentral.ssguitar.com/schematics/axisfuzzschem.gif
It sounds OK, but when i remove, using a switch, the parts drawn in red that Phillip said that makes a big difference in sound i didn't heard almost no difference?

What are these 2 parts for?
It is normally what happened to me or my effect isn't working well?

Thx a lot!

I suspect they are there to kill RF. I have never heard a difference with them in or out on the Axis Fuzz I built.

thx doug...you take a stone from my heart

Hi
they not only kill RFI but if the output impedance of the 2N3906 is high, it will roll off high audio frequencies, too.
If that 100k resistor sets the output impedance of the 2N3906 (which my fuzzy brain isn't sure about today), then there will be lots of roll-off with these components fitted.
cheers

It takes out *hiss*.

I remembered this thread from a while back:

This should help shed some light on it.

Thx a lot...now it's clear!
