PaulhParticipant
I am not an expert by any means. But if you would like to get your project going quickly,
go to DIYstompboxes.com , join the forum , and post your project in “Building your own stompbox” (create a new topic). Describe your issue(s) but you best include the circuit diagram, and photos top and bottom if you can.
They will have it figured in a few hours.PaulhParticipantI don’t see 2N4088 (discontinued)
PaulhParticipantI had a hard time getting my 1970’s era muff fuzz to work. Found a bad resistor.
So:
1) Check General Guitar Gadgets for a circuit diagram (if not here)
2) Check for bad solder joints
3) Check all resistor color bands to make sure they are correct (That was my problem, one was incorrect)
4) Try a new electro cap, they do dry out over time.
Hope this helps. That circuit is a tight squeeze in that small enclosure.
PaulPaulhParticipantPicture 3…
Found synonyms for Smooth Attack and Level.
Hence Fizz Foam and Fuzz…PaulhParticipantPicture 2
PaulhParticipantWell decided to make my own box and attempt the Axis Face.
Sounds great and the three controls work well.
Electronic parts from Small Bear, Amazon and Mouser.
And thanks to Fuzz Central and Bret Robinson.
See 2 more pictures below….PaulhParticipantMeant a 25 watt iron.
PaulPaulhParticipantThank you for the interference tip.
Look around for decorative wooden boxes.
Some have hinges, some inlays, most reasonably priced. Wooden cigar box for big circuits !
Get the right size and you have lots of room to do point to point work.
But seems like through the years smaller and smaller is the direction.
Whats next Nano Fuzz? How about a circuit embedded on a guitar pick and blue toothed…..
Oops I better patent that !
I used 12 ga house wire as a ground from the input to output jack.
Another piece for a 9v rail.
Larger wire does not work with a 1/4 watt iron.
Tried to solder to a penny flattened on the rail tracks…did not work.
Would need to use propane to do that.
My laser cut, made holes and etched the black plastic that I JB Welded the IC socket on to.
Switching color coded transistors (not shown) is like plug and play.
At the end of the day I like big wooden boxes….PaulhParticipantLast.
PaulhParticipantNext.
PaulhParticipantBigger pics.
PaulhParticipantWell here it is.
The Fish Fuzz.
Has an IC socket to change to different transistors (I have 4).
The box cost 3 clams at an antique shop down the road.
My laser cut and etched on this project.PaulhParticipantYes like I said 1N914 is silicon ! Bought them on Prime, free shipping…RS is long gone, like who is next.
Got the positive ground version on a bread board and have tried 1N34A Germanium without much change, I like the 914’s.
Also just tried to put a 100pf cap between base and collector on Q2. No results.
How about the ele cap, what might that change ?
Thanks for the thread..
PaulPaulhParticipantThe diodes in that old Muff Fuzz are very small like 1N914, so I guess they are germanium.
The circuit in that little box was made very tight, the diodes were soldered with the leads “nonexistent”.
Surprised they did not fail.PaulhParticipantHere is the circuit for my 1978 (when I bought it) Muff Fuzz.
I changed the 10K resistor to 68K to make it work.
It has a Positive ground so, I guess you are not supposed to use it at the same time with other Negative ground devices.
The elec cap is 33uf and I have seen 47 and 50 used….whats the difference???
Also try 2N3904 and 2N4401, they make a different sound.
Have fun, make sure all grounds are made….
The voltages are way different plus depends on the actual v of the battery during the test:Nearest amp
