Hey everyone,
First of all, forgive me for my massive beginner knowledge...

I'm trying to build the Antiquity Fuzz listed here,
http://www.diystompboxes.com/analogalchemy/sch/antiquity.html

but I'm currently not getting any good results.  Last time I connected my 9V, my transistors started getting hot, and I'm not really sure if that's normal or not.  Also, I connected it through an amp I'm getting some fuzz (I think) but the volume is really low.

I've attached a picture of my breadboarded circuit...can anyone help me?  Sorry again for my newbie-ish post, but I'm really struggling just to get this simple circuit working.

Thanks In Advance!

Can't see where the input and output are going to but assuming they are good, I notice that the collectors and bases on both transistors are sitting on the
same rails, which means they are connected.  They should not be oriented that way and should not be connected like that.  They need to go perpendicular to the
way you have them aligned.  Does that make sense?  Check out the tech pages at beavisaudio.com.  Go to the tech pages and find the "from breadboard to reality" link and that will show you how to lay things out on a breadboard. 

Good luck....

I rebuilt the circuit and tried connecting the circuit up...when I move the knob of the pot I am generating a great deal of noise/fuzz, but I am not receiving a guitar tone.  I've attached the newly built circuit and labeled the inputs and outputs..can anyone help?

Thanks again!

You have a wrong understanding of this testboard. Theese lines that are marked Red and Blue. They are only connected in the group. Your powersupply is not connected to the circuit. Because only 5 points are connected with - but there is nothing that will lead the - to schematic.

looks to me like you have an understanding of the layout of your breadboard now. most of it is ok, assuming your pots are ok ( we can't see em), except , looks like your input diode is backwards, and you have too many things trying to share q2's base. you need to separate the 470 ohm resistor from the base of q2 to get power to the transistors correctly.

in the photo, your red power wire popped out but i think i can see where you had it hooked up. go over that section again paying careful attention to the schematic. you are getting pretty close.
my life is a tribute to the the great men and women who held this country together when the world was in trouble. my debt cannot be repaid, but i will do my best.

Check out my tutorial on how to use a breadboard:

That should clear up any misconceptions about how it works. The tutorial that follows:

will walk you slowly through setting up a Fuzz.
