Hello everyone,
New to the forum so if the description of my issue rings a bell to one of the thousand existing threads, a reference to it will be appreciated.
I hope I’m able to explain my issue without letting my frustration get in the way. I have an AXE FX 3 unit which has taken it’s fair share of time to ramp up. At the beginning I was getting some noise filtered in the signal and I though it was due to my learning curve process. But now, after various months using it and tweaking I think this noise issue is not due to the lack of knowledge on setting the unit. I have tweaked the gate, I/O configs for the noise to floor ratio, fractal blocks, etc...
I know there are many external factors that can add noise to a signal, but recently I did a test moving my unit to different places at home just to get data, and it appears that external light sources (flourecent light bulbs, screen monitors, laptops, etc )are not a factor. The outlets I used appear to be grounded yet I still can hear embedded in the signal an antenna interference type noise (that mix of bad grounding and hum).
In the guitar is most noticeable when I palm mute on the low E and A strings using high distortion amps with a humbucker guitar. In the bass (Jazz bass) this is most noticeable when I use a DI signal and just a drive block (B7K), using a bass amp appears to help reduce this noise although it does not go permanently away.
My fractal unit is connected into a furman power source so I would expect the furman to filter the noise but it doesn’t. More over I have also tested connecting the fractal unit directly to the power outlet and the same noise.
I have checked the guitar and bass (3 guitars and 1 bass) for ground issues and all HW appears to be making connection (bridge, strings, I/O jack, pots, SW) and is not that the noise signal is boosted when I touch the strings (me making an antenna), is more like the signal is permanently embedded when I play. I have tested several cables, new and used and the result is the same.
Finally, when I use the USB interface to record, I notice that when I change the DAW input source from the latop's default sound card to the AXE FX3 I hear a really dim high frequency pitch in the background, when I switch back to the default onboard sound card, the pitch goes away.
I don’t think the set up has any play since I’ve tested moving just the fractal unit to different locations to see if my location, rack or setup has any play, and the issue goes where the fractal unit goes. At this point I’m out of ideas on how to trouble shoot the unit. Any recommendations on what else can I try to pin-point the problem will be appreciated. Before looking to get this unit into maintenance.
Thank you all. Best regards
