Digital amp modelers - high gain noise

[nepan40]

Hallo to everyone! Hope someone will help to understand what is wrong with my gear.
I have digital amp Yamaha THR10 and recently got NUX Amp Core studio to use at my home recordings but both units, show same issue with high gain settings it is some kind of after noise ... If I'll make single palm mute stroke there will be noise after for couple of second, similar to reverb but with digital crack+ground-loop and it is strong and after it fades.
I have strat type guitar SSH even on humbucker position. Gate effect is turned off but even if I just touch a string with a pick there wil be this after tail or even if I knock the body of the guitar with the finger.
Some people saying to use noise gate but to me it kills sound to early.
When I'm using my old transistor amp - Laney LV100 everything is fine but to record amp is a bit of a hasl so I hoped this emulations will solve it but at this moment lalala... Just asking for ideas of what it can be? And am I the only one with this kind of problem?
Today will try to run it through DI box.

You need to record it for us to have a better idea.

But some questions:

• Does the noise go away if you just reduce Gain on the high gain setting? How high do you run your gain?
• Do you get the same issue if you use the THR10 with batteries instead of AC adapter? Would rule out any mains noise issues.
• Does the noise gate solve it? Especially if you set the gate threshold very high.

Ok! Thanks! Will make samples today

Try high and low cuts.

It’s most likely not related to the digital modeler. Everything from your pickups, to the guitar wiring, to your cables, and anything else that is a part of your signal path can pick up interference or introduce noise in your signal and the more gain you add to that signal the louder that noise becomes. When you hit the strings you increase the level of the signal which also increases the level of the noise

How are these things hooked up?
Very very often things are related to these:

- USB cables and ports, often causing ground issues.
- Power supplies being less than great.
- Yet some more ground issues. Sometimes it might be a ground loop, sometimes it might be the ground not being solid enough to supply proper shielding.

That's a lot of variables but sometimes there's an easy fix around. But you'd need to supply your exact setup information.

I feel like you could have a generalized sticky on this subject in every corner of the internet and be good.

I know what you’re talking about, I ran into this when I first got my AxeFX and I’ve seen other people get annoyed by it as well. It’s like a quick hiss/chirp at the end of a palm mute and it’s basically the result of us being spoiled by low noise in the digital world. I can’t explain it scientifically, but I believe this is the signal to noise ratio and if these were tube amps, we’d be hearing that hiss 100% of the time the amp is on, but we’re in the digital world where there’s likely some kind of internal gate to shut it off, outside the gate you have control over.

I don’t know if hearing it through the amp itself is bothering you, or hearing it in recordings, but I would try raising the volume of the amp and lowering the volume of your interface. I think once you get your guitar loud enough you won’t hear the hiss quite as much.

It's the modeler :-)

i think i know what OP is talking about. yep hate that cracking noise (after palm mute) but always thought was inherent to all modelers. kinda learnt to live with it.

or any high gain real amps behave this way as well? i've no idea. Never played through a real high gain amps.

Not the same sound, instead you get a continuous “SSHHHHHHHHHHHHHHHHHH” of white noise. It’s not terrible, a noise gate will get rid of it easy enough. Some amps are louder than others with it, I’ve had some noisy 5150’s that needed a gate or it was hiss city.

The way you guys describe this it sounds like a built in gate trying to clamp down on the noise floor slowly without getting in the way of the signal.

Fwiw, I used to use a gate with my last analog amps but almost never do with my modeling based rigs.

For me, issues usually only arise (if at all) when dealing with computerstuff at the same time.
Connect things straight to the USB port of the Macbook = bzzzzz.
Connect things to the USB dock = less bzzzzz.
Insert a HD400 (galvanic isolation box) = no bzzzzz.
But, and that's the super annoying thing: It could as well be the other way around. And anything inbetween. Always related to what's connected at the same time, whether I'm using FX loops, etc.

Others than that, when just playing my live rigs through whatever monitors, noise is the last thing I need to care about these days (the only thing I sometimes need to look at is groundlift on/off on whatever DI outputs).

I hate that. Sounds analog.

I’m pretty sure that’s exactly what it is.

Don't forget transformer hum too

And boot time. You turn on the power, then have to wait a few moments for things to warm up before it's ready to go...
