is my unit broke, 2and kemper in 1 week-UPDATE issue fixed

mnewse614 · Apr 21st 2017

Can you guys please help me? So I received my Kemper a week ago and already exchanged it for another new one thinking the other one was damaged, but I am getting the same issue. Here we go, I am using the Cobra profile on rig exchange and the Fortin model JVM Red, when having the am[ gain up and using a green screamer to boost I get this high pitched digital noise. The green screamer is set to gain 0 tone 7 and volume 5. I am using the noise gate 4:1and a parametric eq to boost 80hz a little. If this can not be fixed in any other way than having to compromise my tone I am afraid the Kemper is not for me, anyone else experience this? have a fix?

alright I have messed with the systems settings the one that goes 60hz or 50 hz can't remember the name no go, changing cords guitars etc no go, sound is from all outputs and using both inputs, the units are brand new

I have tried 3 different poweramps to cab, a pair of studio headphones and my hs 8 monitors. I should add there's no clipping input and output stays green on hard attack

Hmm... this sounds like a HF disturbance for me.
Something in your wiring at home?
Have you tried it at another place?

I have used 3 different guitars, 4 different cables, 3 different amps, yahmaha hs8 and also headphones all get this same noise. When I had the first unit I took it into Guitar Center and tried different cords guitars etc and still no different. On the power amp I run monitor out no cab and its set to -6 output on gain staging my amps, my clean sense is at -5, distortion sense at 0. My chain is the COBRA profile gain jut over half, noise gate 4:1 thresh at 5.5, input gate at 3, green screamer is gain 0, tone 7, volume 5, then and para eq 3db boost at 80hz and 1.5 boost at 125

Ok, got it. Have you opened a support ticket already?

mnewse614 · Apr 22nd 2017

and its only the Kemper taking it out all goes away, also that noise will stop after i play then start back up again. If i turn off the green screamer it will go away, lowering gain it will go away, sometimes after disabling the green screamer it'll come back, then weird stuff like hitting -12 on main will stop it then it'll come back again

mnewse614 · Apr 22nd 2017

Yes I did but really frustrating and hoping I am missing some deep editing or something, this is not a great way to start

Where are you located? Perhaps there's a forum member somewhere near you that could come by ...

Were you by chance wearing some kind of HF device like a cell phone at all times you have been experiencing this issue?

I wonder if maybe it could be an internal feedback loop of sorts? Hmm.... I've heard this sound before (not with the KPA), I just have to rack my old brain and try to remember what/where the scenario was..

Is this just with those rigs you use from the exchange? If you use a Kemper rig from a rig pack and same settings, do you get the same result?
