Hiss Remover

    Do you guys have the same problem with highgain sounds ?
    some sounds just have too much hiss and it is possible to remove a bit hiss while profiling with two seperate mics
    so that phase cancellation removes a bit hiss ... i found out that the stereo expander in the kemper can do tat to to a extent but
    if the kemper guys could find a way to do that mono and in post it would be a game changer for me...


    just removing highs makes the sound dull imo

    some of my favorite Bands have this very distorted but hissless sound that i really wand to have

    Crank the noise gate (the input one, not the stomp) to 3 or 4 and see how you go. It automatically takes a fingerprint of the noise and removes it, even whilst the guitar is playing, so I'd see how high a setting you can live with.


    I've found that reducing the gain knob by 1 LED (if originally set to full) makes a huge difference to noise level in most cases, so between this and the input gate, much can be gained, so to speak.


    Cranking the Sag parameter a little to throw a bit more power-amp feel in there might help if you feel that reducing the gain by 1 LED took too much balls away.


    Just MHOs, so YMMV of course.

    Your phase cancelling is doing just that...eq'ing the signal, removing highs. Although not in the broad, shelving way the treble and presence controls on the Kemper will do. You may try using the Studio Eq with a somewhat narrow Q-factor, sweeping through the highs to find a frequency that reduces hiss without sacrificing too much clarity.


    That said, I've never had a hiss problem with the Kemper. Even on clear high gain profiles. Nothing remotely like the hiss in your amp example 8)

    @ trazan: i already do that with the studio eq it is always around 5000hz but a eq is simply a completely different thing then the phase cancellation ...


    lef38: no shielding problem at any of my guitars


    and thanks mr. monkey-man i try it !

    do you have an issue with profiles or with the amp when profiling?
    a profile of an amp will actually have less noise than the amp itself. this happens when switching back to BROWSER mode.


    also, as already mentioned, the Noise Gate on the front panel is quite powerful and does more than just gate the signal (like the stomps do).
    using phase cancellation to remove the high end sounds dangerous, since this creates a comb filter effect, affecting much more than just the targeted hiss.

    Yes, it's not the exact same thing as using regular eq, but the reason you get less hiss is still that the hissing frequencies are reduced/cancelled. At the distance where the 57 is placed in the clip in the end, it will cancel out at about 5 kHz and double at 10 kHz.

    cool thanks you two! i'll try it out


    since i only use the kemper for recording it is a problem with the profile... i made a few profiles myself with this dual micing technique and these are cool but now i found a few better profiles online
    but these have this fizz ... and it would be a cool tool if i could remove this fizz like with this micing technique because i'm a bit unhappy with the results when i have to remove the fizz afterwards


    one main problem for me is having enough saturation and pressure but at the same time not as much high end fizz ...
    i imagine something like a multiband phase doulber ... so you double the signal just between 4k and 7k to get rid of the fizz but leave the rest untouched ... and the good thing about that comb filter effect is that the gainstructure still is similar whereas normal "cutting" chang much of the sound itself ... like in the video the natural combfilter effekt ... i don't know if this makes sense xD i'm not a expert but maybe ther is a way to do it


    another thing i always to to make that static fizz a bit more lively and organic is tube and or tape saturation ... (the blockfish is great for that imo) i never produced any guitar tracks without the saturation so maybe that would be a cool tool too ... (haha oh that word asthetics "cool tool too") :D


    But as i said i will try the things you recommended :) thanks again! :)

    Would be interesting to know where a hiss in the distorted profiles comes from. The Profiler of course doesn't "copy" the amp's noise, and has got no cranked-up circuitry or tubes.
    I would expect it to not only be much lower of the original rig, but almost missing at all, since the Profiler's preamp and the majority of the HPs and active cabs are more silent than a tube amp @ 11 :D


    Pretty sure I am missing the rationale behind the whole fact :/


    :)

    I tried it and it is indeed better now but the pressure is almost gone when i trun it way up ... hmmm

    yeah but cutting to much of 5k will lead to a dull sound that's why i'm looking for another solution ...
    the thing is it's not the fizz alone it is the rather cold sounding fizz ...



    I found one solution now.
    I use the dod 250 preamp in front of the Kemper an if fixed a lot of the problems i found with my sounds,
    the fizz sounds a bit more organic and when i turn up the tube shape, bias and the power sag it really fixes the problems


    one thing is left though


    in cubase i use saturators to make the sounds more "in your face" it would be so cool if a saturation effect would be in the kemper

    I have some profiles with lots of hiss, most without - I did a profile on my Boogie TriAxis (bedroom, not studio...) and the dog started barking at something downstairs... Amazing, the profile contained a dog barking in the background. Wish I had saved it - in the moment I thought it was just screwed up, but should have shared that in the forum!


    Next time I set up for profiling I'm going to have the drum machine or other noise in the background and see how it comes out.


    Thinking about other "crazy" profile techniques - tune a 12 string chromatically, take Piezo out to profiler in, drive the thing with a vibration transducer or a speaker pointed at the back surface. Maybe try one with a box of beads in front of the speaker. Pie plate in front of the speaker... Lots of opportunity for creative lunacy.

    I'm having less or more the same problem, when I'm using modeled guitar sounds from the GR-55. The GR-55 adds quite some hiss compared to the normal guitar sound. I don't go through the GR-55 for the normal guitar sound; I use a Boss LS2 line selector to switch between my normal guitar sound and the modeled guitar sound. The normal guitar sound is just fine. Only the modeled guitar sound gives too much hiss. But it's very handy (for example to use alternate tunings). I have to put the noise gate on the Kemper much higher for modeled sounds. Was also wondering if there are other solutions.

    I really wish you'd have shared it, rmesic.


    I didn't think that would've been possible, especially being so far in the background and only transient in nature.

    i foudn a gear rundown where alexi laiho explains that he always has a chorus pedal activated to "smoothen out the highend" ... so yeah
