Fuzz Face win

after 5 tries i finally got the fuzz face to work. the only prob is its kind of dissapointing. i guess i was expecting more from a classic. hooked up to my ts9 it sounds sweet. oh well i can knock that one off my list.

What exactly don't you like about it?
Don't give up so fast.
It could be a million things... Transistor choice, biasing, room temperature (if you used Ge components), etc, ad nauseum.
The FF has been through the trenches and back and if you ever knew it, you wouldn't recognize it a day later.
I'd say tweak the resistors here and there, try different transistors, all kinds of ways to pull new sounds out of it.

i built the regular dallas arbitor fuzz face, got that to work and did the jimmy mods. i used the ac 128's as trannies. i didnt put in the 2k pot (dont have any) might try 5k

i think i was looking for more fuzz. ill have to plug it in and see

For the 2k pot, try strapping a 4.7k resistor across lugs 1 and 3 on a 10k pot.
Did you get your mods from the Geofex site?
If not, I'd suggest going there and doing some reading about your new beastie and maybe some questions can be answered.

BTW- Glad to hear you got it working, I know the general quirkiness of those old transistors sometimes makes things difficult.

Bad Chizzle

I'm with edvard on this one. I built the silicon version and was disappointed until I Made almost all of the resisters trim pots and replaced the transistors with low noise high gain bad boys. Then I just tuned the thing by ear. Now my Fuzz Face actually has a face on it! Also, I can get all kinds of sounds out of it just by opening it up and throwing a new adjustment on a couple things.  I went with the npn version. Some circuits work well when you just build them part for part from the schematic. This (I believe) is not one of those circuits! At first I was frustrated by this fact, but I have changed my thoughts on it because it creates a great learning experience!

yeah this is the where i got my schematic.

i get the fuzz but my pots dont seem to work. you got to listen real close and you hear a real subtle change. the vol pot dosent work at all. the fact it fuzzes makes it for me lol. i put a 3pdt switch in( the prob is prob there- i have no luck with those things) off board wiring is my enemy right now.

ill try the resistor across the pot lugs and see what that does.

i had to solder all the runs, i just figured out how to etch my own boards. there is prob a solder short somewhere. i guess i need to etch out a real board and try again. (knock on wood)

It's a finicky circuit, that's for sure. Don't give up on it though. It's a great circuit to start learning some theory with. i built two before I finally "nailed" it. http://www.aronnelson.com/gallery/main.php/v/rousejeremy/audio/Germanium+Fuzz.mp3.html

Another thing to look at is the Fuzz Factory... as it's just a Fuzz Face with Booster, Adding a Booster (LPB-1 Perhaps) Afore hand might push it further into what you want, not to mention the values there that are ripe for changing to affect the circuit, being so unstable, alot of simple changes could make it what you want.

Otherwise, More Fuzz, ToneBender it.

edvard

The fact that the volume doesn't work tells me something is definitely wrong, at least with that part of the circuit.
Read the De-bugging thread and VERY CAREFULLY go through and double-check your circuit again.

If off-board wiring is your bane, then pay more attention to that at first.
Make sure EVERYTHING goes where it should.

In the end, it'll all be worth it, I promise.

  First one I finally got going ''popped-on'' and I knew for sure the 2Q FB amplifier was definitely boosting, and distorting.

thnks guys. school started back so time is something i dont have much of, but will debug the thing when i get a chance.

petemoore

  Start with node 1, count the number of connections shown on the schematic, the values and polarities.
  Compare with the measured number of connections, values and polarities on the physical board, everything has to match.

I like the stock fuzz face better than the "Jimi" mods.

clamup1

now it is a win. everything works. thanks for your help guys. now to work on the angel.

edvard

Cool!!
So is the sound like you expected or better?
What was wrong?

before the pedal would fuzz, but none of the pots would work. when the switch was pushed you didnt get anything. i have a 500k lin in place of the 1k lin. i dont have a 1k lin. by the way are the a's lin and the b's log?

i was messing with it yesterday after i finally got it to work and i like it alot. im gonna mess with some more fuzzes and see what i like more. im thinking about doing the Big Muff next
