10 uf electrolytic cap instead of a 2.2 uf

As above, can I use a 10 uf in place of 2.2 the schematic calls for ? will be same 16v.
If not how come?

It depends.  You have to post the schematic. 

My guess is that the 2u2 is in the audio path.  In which case you'd be better off with a 1u.  But again without the schematic, just a guess.

Thank you for responding. its a SI fuzz face I found on the web with step by step instructions that I want to give a try on a breadboard. I'm new to breed boarding. I've always just put together MB boards or Tayda boards. I have a bunch of caps and resistors pots and diodes just no 2.2 or 1 uf electrolytic caps though :)

If you're going to breadboard it, I'd suggest you try it with a 10uf and see if you like it.  It won't explode, so experiment. 

Put two 10uf in series to get 5uf, see if that makes a difference to the sound.  That might help you decide if you need the 2.2

The other thing you could do is read up on the fuzz face... geofex has a really detailed article here http://www.geofex.com/article_folders/fuzzface/fftech.htm

You'll see in the above link that the original circuits used up to 20uf, so I don't think it will matter much anyway!

Ahh, and having just looked at you schematic with my glasses on, I see you probably mean the other cap.  That one it's still fine to try with a 10uf, it won't hurt.  It might have more bass with the larger cap?  You could try a 100n if you've got one of them.  Experiment.  You might end up with something cool sounding.  🙂

And yeah still read the geofex article, it will explain what all the parts do, in way too much detail, if you are wanting to learn.

Thank you for the response  will read the article
