Thanks a lot for your reply! I'll try to play around with that. I failed to mention in my original post that I've not only been working with the Deluxe Vibrato. I also have a preset with a Brit Trem Bright into an Ownhammer 4x12 Marshall IR, which gives me a similar kind of problem. Though I guess maybe that amp could conceivably be too bright for what I'm trying to do too..

I'm using the HX Stomp as my recording interface, amp sim and Swiss army knife effects unit. I love the ability to reamp the signal, double (or triple, or quadruple, or..) up on tracks and tweak the sound as it is needed for the mix. However, one of the integral parts of my sound is Superfuzz style fuzz sounds for guitar. And no such pedal that I've tried so far sounds acceptable into the HX Stomp. There is this high end fizz overlaid on the sound that ruins it all. I've provided a sound example of this in the attached Soundcloud recording. In this recording, the Superfuzz side of my Dwarfcraft Silver Rose is going straight into the input of the HX Stomp, with a US Deluxe Vib amp followed by an Ownhammer Deluxe Reverb IR, and some light plate reverb. First, I demonstrate the clean sound (which is, according to my preferences at least, good), and then the scooped fuzz mode on the Silver Rose, and then the mid-boosted fuzz mode. The problem is especially prominent in the scooped mode, as I take it that most listeners will be able to hear. Superfuzz pedals are supposed to sound nasty and extreme, with a velcro-like quality -- but this sound just isn't right. By contrast, I can link you to a little recording I made of two other Superfuzz style pedals into the Two Notes Le Clean preamp with built in cab simulation, straight into my interface. While the Le Clean is much more limited as an amp simulator (it really only does one sound, with no tweaking whatsoever possible of the cab emulation), this sounds good to me, without the problem displayed by the HX Stomp in this use case. It doesn't make a difference if I run my fuzz into the input of the Stomp or in the effects loop. Changing the impedance settings doesn't help much -- I can at best remove a little bit of the unwanted fizz, but at the cost of dulling the whole sound so much it becomes uninteresting. The closest I've gotten to getting rid of the problem has been to put a 10 Band EQ in the HX chain and completely cut the highest frequencies. This has given me a sound close enough to what it's supposed to be to be okay for me to jam around with in headphones and sketch out ideas. But I am now laying down tracks for a release, and this just isn't gonna be good enough for me to want to put it out there in the world with my name on it. I should also mention that I've tried to eliminate the explanation that this could be something having to do with how the Helix's amp and IR processing handles signals, by taking all of that out of the HX chain and running an Atomic Amplifire Box as my amp and cab modelling after the Superfuzz in the effects loop of the HX. That still sounds bad in the same way -- even though the Amplifire Box + Superfuzz combination sounds good directly into my Focusrite interface. So I'm suspecting there is some weirdness going on in how the inputs of the Stomp handle the impedance from this kind of pedal? In a way that can't fully be rectified with the help of the impedance setting on the input block of the Stomp. Alright, that's all of the relevant info that I can think of right now. Does anyone of you kind Helix forumites out there have any further ideas about what could be going wrong here, or any ideas about what more I could try to do to solve the problem? As it's currently looking, I'm gonna have to record all my parts that require these sounds without the Stomp (using my Amplifirebox into a regular audio interface), thus losing out on the benefits of being able to reamp with the Stomp (and also necessitating that I keep all these parts of my setup for when I move the next time, rather than be able to use the Stomp as my all in one interface and amp simulation solution).
