Does FIZZ apply same to high gain analog stompbox

[rogeryu_ph]

Guys,
I did research on this but still I can't grasp what they saying annoying FIZZ sound on on high gain settings. Maybe someone here RG, Paul and others can explain more on this.....

I expect they just mean 'hiss'.
The kind of hiss you hear if you are listening to a fizzy drink.
The kind of white noise you get from noisy chips and transistors sometimes.

for me fizz has always been that sound you get when gain is maxed out and you just seem to get way too much distortion/compression making notes/chords sound fizzy ... especially amongst higher frequencies

... this is a completely subjective term though

Here have a look on this review;

It includes sound clips but i still don't get it 

If it is true, does someone here in DIY community has made one?
I know many of us also has MFX this may be valuable if we can diy this thing...

Your comments will highly be appreciate...

Well in that review - clearly they are talking about something completely different from the simple high freq random noise I was referring to.

Fizz  is, in my experience, a form of harmonic content whose properties make it seem like an uninvited extra to an otherwise decent distorted tone; a bit like the buzzing one might hear from springs on a temolo or between the nut and tuners, or spare change or keys sitting on top of the speakers or amp.  The fizz is produced by the circuit, but by virtue of its other characteristics (a sputteriness and sometimes gated quality), it seems disconnected from the rest of the harmonic content.  Wouldn't surprise me a bit if it was somehow ultimately related to the use of diodes in many clippers and the "threshold" effect that diodes and their fixed voltage drop present.  Maybe that's why I always seem to like the sound of clippers where the top end is filtered out prior to clipping.

I think it's referencing harmonic content. Lots of high order odd harmonics in the signal that are unrelated to the original signal. The sound of "bad" distortion. Usually being the difference between unfiltered opamp or transistor distortion compared to class A tube amp distortion.
Then of course some people like that sound. Over the top fuzz is pretty much "bad" distortion taken to an extreme level. And it definitely can sound "good"!

For me, "Fizz" is the additional low volume, but nevertheless audible, extra though unwanted
"harsh" harmonics riding on top of the wanted harmonix from any kind of overdrive/fuzz,
that originate from supposed to be "linear" components like opamps,
that are (unwantedly) clipped at the power rails, and send these fizzes throughout the circuit,
regardless of how well the wanted fuzz`s treble is being shunted by caps.
Happens with multi-channel FX too, where the supposed-to-be muted channel
adds unintended clipping to the output...
