0.01 and 0.001 uF

[DaKurt]

Ah, I bought a wrong capacitator. Now a question, can I put a 0.01uF cap instead of the 0.001uF here:

[smoguzbenjamin]

yup, but the difference made by the 'thickness' pot will be different, because the 0.001uF cap will roll off more bass than the 0.01 uF cap

[DaKurt]

allright, thank you

Has anyone ever tried designing a 'BazzFace'?  Seems like a pretty easy idea to implement...

[B Tremblay]

Tim Escobedo includes a "Bazz Face" with his Many Faces of Fuzz article.

Thanks for the link B.  I was thinking more along the lines of a diode from collector to base though.

[DaKurt]

So I built this Bazz Fuss Deluxe...and it works and soungs kinda cool. But it's more a distortion than a fuzz. Can I get more fuzz when I change the diodes and the capacitor (back from 0.01uF to 0.001)?

[smoguzbenjamin]

The cap won't make much difference. The diodes have a big effect on clipping though. Try different ones.

[DaKurt]

and if i put in a 0.0001cap in or so do I have even more basses?
and what if I delete the cap? More bass or does it sound worse then?

[smoguzbenjamin]

Smaller cap = less bass. Removing the cap will let all your signal come through, and you'd be putting DC up the input which is a bad thing.

[DaKurt]

but I said I put a 0.01uF cap instead of a 0.001uF, so now I have more bass, right?!

[smoguzbenjamin]

Yup, you'll have more bass. Just remember to always have a DC blocking cap.

Just finished this build and I really like the sound.  My question is - I didn't have a 1klin pot for the DIRTY control - had a 5K linear.  - what resistor can I add in parallel to get the pot in the right range.  My calcs says a 1.25K  should do it - would I then solder it across lugs 1 & 3?

Thanks

BILL

[smoguzbenjamin]

correct. You could just use the 5k pot, it will just decrease the amount of amplification more. Which is to say, the range of the control will be greater. That doesn't have to be a bad thing though

I used a 4.7uF input and a 0.22uF output when I tried that circuit and it sounds great on bass guitar.  I also put in an orange LED for the diode and it has a great ballance of warm fuzz and low end when used with a P-bass.  Who needs pots?  

[DaKurt]

what's a dc blocking cap?
This schematic already has it right? What if I don't have a blocking cap?

[bobbletrox]

That's the 0.01uF you put in.  I guess you'd say it chooses which frequencies get into the circuit, and also stops DC current from going up your guitar lead.  I think that's right.

[smoguzbenjamin]

If DC goes up your guitar lead, and if there's enough DC there you might actually fry your pickups, depending on quality. That's the point of having a DC blocking cap.

The cap does filter out frequencies below a certian value, a neater way of doing this is by using a passive high pass filter which is a cap and a resistor to ground, in that order.
