Strange metallic ringing sound

    Thanks for the replies hopefully we can figure this out together. I'm on the latest firmware but I will double check that later just to make sure. The profile I recorded is my own that was made quite a while ago. I did wonder my self though whether it's something to do with the cab portion of the profile because it only happens when playing through a real cab but then I gave that idea up when I realised it was the same whether the cab was on or off.

    Hi everyone


    Just an update on what's happening with this issue for anyone that cares.
    After some trouble shooting with kemper they decided the best thing to do would be too send it into them for repair, I'll report back when it's fixed.

    Well even though Kemper told me to send it into them I received an email from Andertons saying Kemper won't give them a returns ticket unless they can find an issue in-store. So I've been without my Kemper for over a week and it's not even been sent to them. I don't blame Andertons for this because one there not engineers and two I haven't gone through trouble shooting with them so they don't know the exact nature of the problem. So I'm a bit perplexed with what's going to happen next.There was some talk of it being my profile that is the issue but it also happens on a commercial profile of similar gain but I can't remember which of the thousand profiles I have.


    I'd really appreciate if someone could try my profile with a cab and let me know if you have the same issue as me to rule that out.


    It's my JCM 800 profile with out the boost just search Tom South and it should appear or alternatively I could email it if you can't find it.


    I'd really appreciate it because I could do with my Kemper back because I don't have a backup and need to do some recording.



    Just tried it with and amp cab setup and it sounds crappy on mine as well. I've heard this same sound (like a rattling old tube) on a few profiles post FW3, no idea what causes it but some profiles it's more noticeable and some it's not. Better off sending the profile over to Kemper and seeing what they say. It's really strange and could certainly be a FW bug.


    Good news is that your KPA is probably OK.

    Thanks for trying the profile out at least it's cleared it up a little. I did send a backup file to kemper with that rig on and told them which profile as well and I assumed they would have tried it before telling me to send it to them for repair.


    I suppose it still doesn't explain why I heard the same sound on a commercial profile which I assume would be all ok on other people's kemper.


    It's kinda annoying that I was told to send it away if it's not needed

    Yeah, I've heard it on some other profiles as I said. It could just be that these profiles are in some way incompatible with FW3 or it could be a bug in FW3.

    Sorry I missed that part about other profiles so it would seem based on that it's some sort of software issue or something. Still strange that they would tell me to send it in and then tell the retailer that it's not worth sending after I've been without my profiler for over a week. I'm a bit lost with it all and feel kinda let down. Thank you very much for your replies and for testing out the profile.

    Can anyone else replicate the sound I am talking about with my profile because Kemper are saying because XpennoKPA has replicated it then it's definitely a software issue.
    I am fine if it's a software issue even though I wish I had been advised this before being told to send it in to Andertons by kemper but these things happen.
    I just don't want to get my profiler back and it still be broken.

    I get it too with Merged and DA profiles. It's definitely a software thing. I never had it before FW 2.8 and thought it was exclusive to the experimental firmware, but it's there on a substantial number of the Merged factory profiles when playing through a guitar cab, too.

    I miced my cabinet up with a SE X1 but the sound is present even if you plug headphones into the monitor out so bypassing the power amp and cab. The sound is not present when using the main outs with cab sim on only when using the monitor out. That's as much as I can remember with out trying it again with the kemper in front of me, it may be present on other outputs but Im not sure.


    Any help is appreciated

    yeah I remember you saying sambrox that you have heard it before which made me think it was software but kemper couldn't replicate it from my back up which is why they said to send it in so it could be a software issue after all.


    Kemper are trying my back up again just to make sure if it can be replicated or not.


    If it helps my profile was created before merged profiles existed.

    I do want to state that as annoying as it is that I have had conflicting information Hans-Jörg Scheffler has dealt with it really well and is doing his best to get to the bottom of this.


    If I've come across as annoyed it's just because I want to make sure that it's definitely a software issue before I get it back.
