Bazz fuzz breadboard woes

Ok so I just tried to build the bazz fuzz on breadboard for the 10+ time this time I got it working sort of. I can build crazy complex circuits as long as I etch the board I CANNOT breadboard. So here is the problem the vol pot on the effect acts like a clean up pot and doesn't turn down the dist or vol the tele I'm using only works w the bridge pickup w the tone rolled off completely as you turn the tone up it starts to gate and you really have to hammer down on the notes! I am posting pics but wtf I don't know why the pedal won't act right.

did u short the input cap with a jumper?
always think outside the box

No my breadboard actually won't have continuity across that line so I have to jumper the strips... I think once again I can't bread board maybe moving the + side of the electrolytic will help. I'm more vexed by the tone control

here ya go..  



btw check for continuity (beep) on the power rails.

Ill sure try it! Ill bread board it as soon as the family awakes. Also could you give me a breadboard diagram on the amz buffer splitter I want to use it on my eh vol pedal jr. I can build soo much I just can't bread board. It's sad but true but I'm going to figure out bread boarding and eagle! So help me god. And thanks dead astronaut. You are always a help. When I post a thread you are one of the few I hope comment! Where are you from man? States or England?

no problemo, i'm from London UK.

I don't know much, , but if i can help a fellow out i will.. ;)

I believe the input cap should be connected to the base (middle pin) of the trans.

I CANNOT breadboard.

Not so!...you are just in too much of a hurry. Please look in here:

at my example of a breadboarded layout. Take the time to plan, lay things out neatly and square off connections. You'll find that this makes it easier to see your own mistakes, and easier for other people to help you.

Steve I have followed your photo essays to the t time and again but never w any luck. I have etched and built 40+ boards and they work but I can't breadboard an lpb1. I ginuwinely thank its my breadboard. But I don't give up! I mean I can't! Km up for the day in an hr. ill rebreadboard the project.

Hey guys I have an odd q. Do you need to ground the in/out jacks? When I don't I get a serious hum! Ill try reboarding this in a sec!

Yes mate, always ground the input and output jacks.

Sometimes on builds you might see the output jack without a ground wire. That's because the jack is grounding itself through the box.

I always wire them up though.

This is where I learned to breadboard. Go through it a few times.

BTW Steve. Last week you taught me how to etch circuit boards with PNP. Thanks mate they came out great.

So I moved the input cap( it was already connected to base) the pic didn't show it well! The tone knob issue is fine joe but when I leave the effect pot turned up and the guitar vol off I pick up radio freq. can't I add a small cap somewhere to get rid of it.

Breadboards can be pretty noisy, especially with RF noise. When you put it in a box ( and ground the box ) you get some shielding from this type of interference.

The noise will probably go away when boxed.

You can put in a small cap I believe. I'll leave that for someone with greater knowledge to help you on that one.

am I missing something?

why do you need the jumper if you have the cap across the center. isn't the jumper a duplicate that's just shorting the cap?

Buzz

Sure looks like it. Take out the little red jumper.

I put it there bc I thought I wasn't getting continuity across the lines but I moved the input cap 45• to the side everything is on and it works except for the rf frequency! Now I just need to bread board the buffer splitter from amz and then work to harder stuff

You can put a small cap from input to ground toi get rid of some of the radio. Also as Buzz stated boxing it will help.

disabled, I dunno this will help, but I'll tell you anyway.

if you run your battery+ along one side of yr board, and run B-/ground alond the other side, your layouts will start to look a little more like the drawn circuits, + at the top, gnd at the bottom. less confusions.

and if you have some old guit leads, cut the jack off one end, or cut a longer lead in half, and solder and insulate short wires to the braid and the centre conductor. I use these as inputs and outputs for my breadboarding instead of sockets, and if you have a ground wire waving at you loose, you'll be more prone to sticking it in the right place.

you could put a small value cap across the diode, C to B, as well. start w/ 33pF, work upwards if needed.
