Boss GT-1B noise issue

[Baker69]

I get this noise on my Boss GT-1B which is clearly audible (especially through our P.A.), and I have noticed that if I go into the settings and the Speaker Types if I select the very last cab option (which is the 8 x 10 speaker option) this noise disappears? On all other speaker options (or speaker sim off) the noise is still there.

I’m at a loss as to why just this setting solves the issue? I don’t really want any speaker sim but I have to select the 8 x 10 as it is the only way I can get rid of this noise, does anyone have any ideas on this?

Do I understand correctly that this is a kind of noise the 'Noise Suppressor' (placed at the end off the effects chain, set to detect input) cannot fix? I have no answer but suggest you also post in the Boss GT-1B thread, you may have found a workaround to get rid of noise .

*What kind of noise?

*Do you have a low pass filter which can be inserted at the end of the chain?

I’m of the impression that Boss, when trying to parrot a real 8x10, is employing fairly aggressive roll-offs on both low & high ends. Seeing that it impacts each and every patch / preset, I would also re-think gain structure patch-by-patch and globally if available.

Is it a high pitch ground noise? It could be a cable. Try using different cables from GT to Amp, and ensure your bass isn't making noises either.

 

[Baker69]

I don’t use the noise suppression function on any of the presets and I use a separate compressor rather than the built in ones. I have tried the noise limiter but it doesn’t make any difference.

Yes, the noise is a high pitched sort of noise and at one point I thought it was a grounding issue or even an issue with my power supply unit. The fact that just selecting the 8 x 10 cab cures the problem is very puzzling, but as Zooberwerx has said perhaps it is something to do with the characteristics of that particular setting.

The sound occurs using any of my basses and cables.

I’ll post this on the GT-1B thread as suggested in case anyone else can offer suggestions.

Thanks for your help so far guys.

I noticed sounds coming from FX1 Limiter, and Preamp Concert, just in case you're using those I lowered the effect volume also lowering any gain you might have on the GT

No, I don’t use either of those. The noise seems to be on all amp models and effects but strangely in selecting the 8 x 10 cab it silences it.

Do you hear that noise running on batteries, or only via the power brick?

 

[Rooster009]

Is it a solid constant noise or is it a signal clipping noise when plucking a string?

I have a similar noise. Mine is constant, plucking strings or not. Mostly like a buzz or hum.

I'm assuming for myself it has to be the power adapter. I only get it when using it with my amp. It's worse if I use anything else with it. I think I need to get an actual power supply. If I have it connected to my computer and my amp, I can hear the mouse scrolls and stuff, but I never really need it like that. 9/10 if I use the GT-1B, I'm using headphones or playing into my computer for Rocksmith so it isn't an issue, but I don't know how I'd get it to play with my amp if I want to use anything else pedal-wise. I do get it occasionally while using batteries, but I have only tried a couple times because it sucked the batteries fast.

I don't know ... I've been using mine pretty much since they were released (2017?) and I play mine, essentially, the same way you do; either through a P.A. or the "P.A. Jack" (it by-passes the entire front section of the amp and just uses the power section).

I have never had a noise problem.

If it's still under warranty and you can verify it's not of the peripherals (cables, instrument, or power supply), I would advise you to return it.

Sometimes it helps to use another power outlet from another group. In my bedroom I have a lot of 'hum' , but with an extension cord from the living room (different group) my gear is pretty silent.

I have noticed this about the 8x10 cab model on there - it cuts out a ton of frequencies. So whatever frequency your noise is happening at is being cut out when you use that. So what I'm getting at is I wonder if the noise is coming from your bass and the GT-1B just happens to amplify it to be noticeable.

This is where I am at. I'm pretty convinced it is my power, which is why I think the power supply might be my answer. One of my goals is actually to get a dedicated power line put into my office just because the way my house is wired. When I mapped my outlets, my office, my wife's office, and our living room (all the outlets on one entire side of a small ranch) are all on the same line. So even before I started playing bass that's two computers, a TV, and all their peripheral stuff like Fire Stick, monitors, speakers.

I've had an electrician out, and it's all up to code, it's NEVER all on at the same time, and we aren't exceeding the load so we are safe, but I hate it so much. I get anxiety just looking at all the stuff we have plugged in, but allegedly it's ok. But that's why I'm not too set on aggressively trying to figure out what's wrong with the pedal because I think that may not even be it.

I noticed Sunday my GT-1B was making a faint (loud enough to hear solo, but not in the mix) distorted fuzz/clipping like noise when the E and B string were plucked. I verified it was the Boss, because the sound went away when plugging directly into my preamp. Boss was powere by a 9V AC converter with 2A (2000mah) supply. The patch being used was a compressor into a limiter then the noise suppressor. The patch was still making the distorted sounds with the compressor (FX1) and limiter (FX2) off. I found a thread on here stating that the NS causes this even if it is not being used. The poster stated that if you run all settings of the NS to 0, it gets rid of the issue. I have not had a chance to try it yet, but will report when I do.

Hiss is usually gain staging but the noise wasnt hiss. It is more like the distortion from a weak battery. I tried turning down my input, turning down the output, turning down my bass volume, turning down the bass for my onboard EQ, but the fuzz/clipping sound was still present.

 

[winegamd]

I confirmed last night that the noise suppressor does indeed introduce a digital intermodulation distortion. If all settings are zeroed, the noise goes away.

Most of the time I have only used the NS effect with dirt or other effects that mask it. But, when I set up a clean channel (in the past this has been a channel with nothing running, just a clean pass through) for the first time with a compressor and limiter I used the NS to quiet some faint hiss while not playing. This is when I noticed the low square wave like fuzz or a "low battery" type distortion on my E and B strings (the distortion seemed to increase in amplitude as the frequency went down). The distortion completely disappears when the NS is zeroed, though.

That sounds like compressor/expander chatter. If you set the attack and release settings on a compressor or expander/noise gate too low, they can ride very low notes and chatter on and off rapidly.

Honestly though, I tried what you did and I can't replicate it. So I'm not sure what else you have in your signal path... The only other situation I could see this happening, is if somewhere in your signal path you had WAY too much signal into a compressor effect and it was breathing in quiet parts.

 

[winegamd]

Signal input into the GT-1B is at 85. FX1 was set to the vintage compressor/limiter, threshold 63, attack 11, release 37, 2:1 ratio, 17 makeup gain. FX2 is the multiband limiter, threshold 83, attack 83, release 27, infinite ratio, makeup 17. Then it was the noise gate. I tried different compressors and limiters with different settings in FX1 and FX2 position with no change. Only went away when NS was removed/ zeroed.

I posted on there after you suggested but no one has replied!

I haven’t tried that recently as my GT-1B is permanently connected up on my pedal board so I don’t keep batteries in it any more, but I did have a separate noise issue which I posted about some time ago, I can’t recall how I resolved it now, I think it was one of the settings. There’s a chance the power brick may have something to do with it, but again I can’t see how by changing a cab setting would rectify a power supply noise issue?
