Interesting, you could have a point. The noise is there using different basses though.

Boss GT-1B noise issue

I’m going to check out the Noise Supression settings and zero them all as you suggest, it’s worth a try.
You posted in another thread on the GT1B, here is the tread I was referring to:
https://www.talkbass.com/threads/boss-gt-1b-discussion-thread.1430343/page-28
This is the 'general' GT1B thread with potentially the most TB-members on the 'watch-list'.
A high pitched noise (especially if it's somewhat whining) definitely could be a PSU issue. Definitely test it with batteries and stand-alone. Proper testing means taking away as much external factors as possible! Test results from the past do not count, there could be new factors in the equation.
Good luck!
Can you try moving the NS component to the front of the chain? The Boss noise suppressor defaults on the GT-1B are designed to be used at the very front to manage any noise coming directly from whatever you're plugging in. It's not really meant for mid-chain noise reduction. If you want to use it that way, are you setting the DETECT parameter to "NS INPUT"...?
Otherwise if you run it after a bunch of compression, it can't really track noise vs signal easily. I'm all for experimentation, but you're kind-of using that feature in a way it was never designed to be used.
Also, I believe the multiband limiter is MDP. Is there a reason why you're chaining a traditional compressor to a multiband limiter but using a low threshold on both? Are you doing that to get more treble?
Some of the cab settings have serious top-end roll off. If the pitch you're hearing is above the range the cab sim lets through, I could definitely see it cutting the sound out. Do you have access to a BOSS PSA adaptor to test?
I don’t have a Boss adapter but I may have a generic 9 volt adapter somewhere.
It would have to meet the spec of the GT-1B... preferably a switching power supply, rather than a heavy transformer-based version. Not all 9V adaptors would match the max current draw the GT-1B requires.
I did not the NS it at the front because I was trying to use it to get rid of any amplified noise after compression. I did change the input source to NS Input. Last night I didn't really notice that much hiss with it off, so its probably not necessary.
I am actually using a limiter as a compressor. The "vintage" limiter setting is supposedly an 1176 model. I like the way it sounds and it operates the same way since lower ratio's are available. Plus, I like having control of the attack and release time. I am not trying to squish my signal, just bring out some of the detail and brighten up the middle of the note envelope.
The second limiter is to control the E and B string peaks and balance string to string response. I chose the multiband because it sounded more natural. I made the settings choices by listening to what sound natural but kept the E and B from clippling by input at my amp/preamp but still having as much gain as possible.
My Epifani Quest has a narrow window of input gain where it likes to be driven for the sound I want. Too much and it sounds less open, too little and it sounds dead. To keep the sound I want on the D-C strings would sometimes be too hot for the E and B causing them to clip the input on transients. That is why the second limiter is being used.
The cab choice can be found under the Preamp section under "SP Type" You can't really change the settings for a cab, but you can select different cabs. The cabs don't have their own set of parameters.
I went into the Memory Edit settings and you were correct in that the Noise Suppression is in there even though not selected elsewhere. The setting was quite low and I turned it up to 50 and I could hear the noise disappearing as I increased the value.
In addition, I was wondering if the Gain setting on the user presets was a bit high so I reduced the presets I have set up down to about 20 and similarly this also seemed to get rid of noise. The issue now is that it’s possible I may have reduced these too much and through headphones the overall output needed to be increased a fair bit to compensate.
So, I have managed to eliminate a lot of the annoying background noise, however I’m still having to select the 8 x 10 speaker cab option otherwise the noise reappears so there is still something not right. Is it possible to go into the speaker cab settings anywhere?
