I was checking out some old
junk audio gear and found two
perfectly good ac128 transistors
in A reel to reel deck (mullard britan even)
so I had to build A fuzz face,right?
Three days later, I had the thing put together
and it works! The transistors are not A
match so its not the best sounding
it is as far as tone right in the
middle of too nasel and too much bass.
If I could get around the gain matching
thing it would be perfect, if not for one
thing, it is soooo noisy, it sounds like
somthing is turning the hiss on and off
and the hiss is in the background and not
afecting the guitar signal, if I listen to the
hissing I here, very very faintly some kind of
interference, voices in the hiss (sounds like A title track). I built the unit using the schematic
on the technology of the fuzz face web page, with the jimi hendrix mods. anyone have any ideas on how to shut the noise off ?

Unfortunately, the noise you hear is probably from the devices themselves. They might not both be noisy, but the only way I know how test this is to swap in a device that you know to be quiet.

As for the stray RF, at least put the thing in a metal box to reduce the noise. I suppose you live close to a radio station. I've built mine into a plastic box and it doesn't pickup and radio stations at all.

No way pete, I had the thing surgicaly
implanted into my forehead, it's cool, all
I have to do is smack my head into my amp
to turn it on, and then again
to turn it off.......
I guess I forgot to mention
the unit was put into an old reverb
pan that had served it's usefullness
and would reverb no more. the interference
sounds more like cb than radio.
Pete, I know my homor needs work
and thank you for your input.

No doubt Pete, but this being the year 2000
and with people all over the world sticking all sorts of things into their heads, it would not
take A far strech of the imagination to think
someone has or will try this, and they may be
offended. if I have offended anybody with
my poor attempt at humor please accept my full apology here and rest assured, that pete and the
rest of the good people at Ampage will be here to help. Is there A doctor in the house?

The board I pulled them off of
was stamped 1966, it was A wonder
they worked at all. It would have
been cool to have A fuzz unit free
and home built but I guess I can
spring for two transistors.
Thanks again for your help
