    I've been jamming with my Amplifire all morning and loving the tones - but I have noticed a strange decay on the notes that is apparent.

    It sounds a little fizzy / slight buzz to the note decay - mostly noticeable on the low e - and with mid gain settings - once you get into high gain territory it's masked a lot more -

    Does anyone know a good way to remove these unwanted artifacts?

    For ref I'm using preset one - the HBE with the following

    (boost is provide by my Mooer hustle drive on the board)

    gain 3.2
    bass 3.5
    mids 7
    treble 6
    presence 6
    master 8.5

    Cab is a WIlkinson audio custom IR - but issue is still very noticeable with the standard 'matched' IR built into the Amplfire.

    I'm running into my Focusrite 2i2 with all levels on green - using balanced XLR outs - and monitoring via my AKG 702 cans which I appreciate will give some very clinical listening.

    Aux output is at 0db - I can still notice the issue when lowering down to -12 - so don't think any internal clipping is taking place.

    Guitar is a ESP LTD EC1000 with Dimarzio D-Activator bridge and PAF neck.

    Anyone else experience this? Have seen a thread on TGP with similar info - https://www.thegearpage.net/board/i...tes-tails-off-is-my-amplifire-faulty.1636667/

    It's not stopping my enjoyment of this awesome product - just wondering if I can do anything to remove / lessen the noise.

    Cheers,

    Are you on the last beta firmware? if not try to update , once on the new firmware try to export and reimport the preset
    once done try to deactivate and re-activate the compressor... (99%the cause of that problem...);)

    On the latest beta - 4.1.2.1? D'loaded from this site. I didn't have the compressor activated on the patch - but followed your instructions and it seems to have lessened the issue (been jamming since 9.30am so nigh on 6-7 hours now) or my ear fatigue has kicked in.

    Is it some sort of internal gain staging issue with the stock presets? So by exporting and importing and then turning the comp on and off - does this stop the fizzy decay / note issue???!!

    And, if it's a problem has it been acknowledged by the devs and will be sorted in future f/ware?

    Sorry for all the questions, just curious!

    I think that is a "compressor" problem within the different firmware versions this is why I suggest you to export and reimport the presets, in my case this (along with firmware update) solved the problem just my 2cent;)

    Interesting, thanks for the tip - so I should export a preset when liking the tone - ensuring the compressor is on (even if not wanted as part of the patch) then export - import and then turn off and back on the compressor - and this should solve the issue on the patches when I hear it? Bassman / Luxe I'm noticing especially also....

    Yes this is exactly what I did (after update the FW) and this solve the problem for me! to be honest I export and reimport all my presets!

    I have this exact same issue and it's really annoying. Today I decided to build a pach from scratch and see if it's there. Added the Plexi amp, and of course Cab was the only other setting enabled. This decaying fizzines doesn't seem to have anything to do with Gain, as I set it down to 2 (Master at 5), and I can still hear that lingering fizziness. I really notice it with the lower strings, when holding a note or diad. And like Riffmagus said, higher gain tends to mask it pretty well. But I'm playing a lot more with low to mid gain amps and want to hear those notes linger nice and clean (so to speak).

    Riffmagus were you able to permanently resolve this? I cannot imagine having to export and reimport every preset. That's a workaround I'd prefer not to have to do.

    I'd like to hear from Jace on this issue. What causes it and how to resolve it.

    Thanks!!

    This sound is the modeled power amp crossover distortion noise that the physical amps make.
    It's most prevalent in the Plexi, Bassman and Rumble.
    For a real world example, listen to the intro of Van Halen-Drop Dead Legs from 1984:
