Unnatural sounding 'fizz' on sustained notes

After a couple of weeks with my FM9 I've noticed an odd artefact that seems to show up on all but the cleanest tones.

If I set up a 'crunch tone' (maybe a cranked bassman model) and play a single loud chord, as the notes fade away I hear a 'fizz' that gradually comes and goes. It doesn't occur as I actually strike the chord, just as it rings/fades out.

I'm not clipping the input stage (or at least I'm not getting a clipping warning) and have all levels in the path at or below 0dB.

I have to admit that, now I've heard it, it's all I can hear as it is not a very natural sound. It has an air of digital clipping about it.

Anyone got any suggestions as to what it might be?

Thanks.
 
Yes it’s something the actual amps do too. I used to build my own amps and one day I heard the fizz and crackle on the decay. It bugged me and I tried many things to reduce it. I was able to tame it a bit but not eliminate it. It’s something tubes do when you clip them hard.

Listen carefully to a bunch of isolated guitar stems on YouTube from various pre-digital songs. You might be surprised how much fizz and crackly noises are there with the notes on a cranked tube amp.

It’s pretty nuts that they can clean guitar tones up like they do. Kind of like photo shopping guitar sounds.
 
The really good ones are often direct from studio tracks and stems. A lot of great isolated tracks came from the Rock Band and Guitar Hero games. The producers went back to the original tracks for a lot of those parts. Software can do amazingly well at isolating instruments from a mix these days, but there's still often some artifacts that can be heard.

I’ve never heard any amp modeling artifacts on fractal that sound unnatural but I don’t know what you’re referring to because you haven’t posted a clip.

No need to post a clip. Just listen to the songs posted above. Maybe the op is talking about something else but decay crackle and fizz is a thing. Natural for a tube amp.
 
Okay, not able to make a recording today (just too busy) but, a few observations:

1. I was in a bad mood yesterday. Playing for 5 monites today, possibly I overstated the issue. I can hear it but it bothers me way less.

2. Much worse on my FRFR speakers (Headrush 108) than in my headphones (Beyerdynamic DT770). The headrush FRFRs do (IMO) have a bit of high mid peaking so they will really expose this stuff (also makes them nice for clean tones though so no complaints).

3. FYI, an easy way to 'aggravate' the effect is with factory preset 000 (59 Bassguy), scene 1 (crunch bright), channel A and then just dime the Bright gain:

I will, when I have a mo, record what I'm talking about but I suspect I was being over fussy yesterday.

Ta, for all the input.
