Help with fine tuning Fuzz circuit Please

[sonolink]

Thanks for the links, but actually, I was more looking into adding a filter to the fuzz face circuit mentioned in my first post...to learn about filtering and to be able to use any PSU.
I might use your idea for my breadboard though

Cheers

I am FAR from an expert on this topic, but I recall reading a few articles that the sound of Ye Olde fuzz units was influenced by the then-available batteries. For general uses, the only choices were the old carbon-zinc products by Eveready, etc. Allegedly, those batteries had a higher internal resistance/impedance compared to the current alkalines and fancier batteries.

Harbor Freight is a good source for cheap carbon 9v batteries

Yeah the old radio shack 9 volt batteries for 29 cents a piece,

Duane Allman talked about the dead batteries sounding the best but the funny thing is I never heard him use a fuzz box. Maybe it was with the Allman Joys or The Hourglass.

I guess you could simulate the dead battery with a voltage dropping device that would also change the impedance if the power supply. I forget what there called,

Sag?

Putting a ferrite core around the power cable coming from the One Spot might help. A simple RC filter on the power input can help. Try a 100 ohm resistor and 220uF capacitor with a 100nF cap in parallel with the 220uF.

That worked a treat!! (2x 220uF and a 100R resistor in series)
Thanks to everybody for your help, ideas and suggestions!

I finally ended up with this schematic:




I replaced the Smooth pot with a fixed value resistor (1k5) to eliminate noise when Guitar volume is at 0. The guitar volume provides the same function really.

The power filter is very effective and the circuit sounds absolutely great and is very versatile.

Thanks again for your time and help
