I’m a happy quad cortex user, but I do have issues with the fuzz models. They do not react the same way fuzzes do in real life in my point of view. there’s too much high end, which I can only compensate for by lowering the input impedance, since fuzzes mostly have 10K impedance. Am I the only one having issues with it? Or how could I solve this situation? Kind regards from The Netherlands!

I think you have taken the right approach. Selecting a lower impedance and placing the fuzz at the beginning of the signal chain are typical measures taken to get a more authentic fuzz tone with a modeler.
I agree with HonestOpinion - it’s not an issue, you are simply using it correctly.
The way the fuzz interacts with the guitar pickups is by having low input impedance and being up front.
Otherwise, you may get a nice tone, but you won’t get the same response as with an analog pedal, since the responce comes from the interaction with the pickups, which happens at low input impedance.
I’ve got a Redbeard honey badger in front of my QC and I use it with the plugins sounds amazing, wasn’t very impressed with the fuzz tones on the QC , so the reason for buying it as a add on.
Thanks for the replies. I still do not understand though why one needs to manually lower the input impedance. It’s a global setting that affects all presets.

Agree, total PITA on the QC right now. Impedance should be able to be set in each scene. Nice I suppose to be able to assign as a parameter to a footswitch as well, although scenes would accommodate most folks. Hopefully this will make it into a firmware update.
Anyone else having text from a previous post removed when they include it in their response post? Then the post shows as having an edit, even when it didn’t receive one? I got an automated message kicked back saying the quoted text was removed. Why? The text I quoted was from @jorisd, above. Maybe @MP_Mod can answer this one (with my text quoted 
). This has happened the last couple of times I have responded with quoted text. Is there a quote quota?
Bump, don’t want to hijack this topic but nobody else is having this issue with quoting?
Hi @HonestOpinion , I looked at your history etc, I don’t see any issues with your account nor do I see and edits made on yours or anyone’s behalf. It might be the original post was somehow modified and or deleted but I don’t see any evidence of that occurring. I am sorry you are experiencing issues with posting and or quoting a previous post. You are using the standard reply button?
In addition to making impedance a preset/scene level setting instead of global, the Helix also has an Auto impedance global setting. It can be set to either the first block in the signal chain, or the first active block in the signal chain (skips bypassed blocks at beginning of chain till it hits the first active one). Pointing this out just to elaborate on alternate approaches.
Hmm, I am starting to wonder if it has something to do with whether or not you grab the whole of the forum member’s post, or just a fragment. In my post above I grabbed just one sentence from @jorisd 's post to respond to and that worked properly. In my previous post above that one, and all the ones that I remember failing, I quoted the entire post.
Anyway, thanks very much for checking. It is definitely failing consistently; just not sure what combination of actions precipitate it. Btw, I am on Windows 11 using Microsoft Edge.
No worries HO! We haven’t received notice of any errors with replying /quoting to a post as of yet. We will keep an eye out for similar issues and thanks for posting and providing the additional details.
Btw, I can see my previous comment was confusing. I was not implying that the quotes were randomly disappearing after the fact from my posts. The message about the quote being removed is visible when I click on the icon showing the edit (that I never made). You know, the icons that show up that look like a pencil to the right of the number showing how many edits. The forum message says the following: “Automatically removed quote of whole previous post.”
Perhaps this confirms my supposition of it being an administrative configuration option on the forum that prohibits quoting an entire post? I guess whoever administrates/configures the forum (you? - moderators and administrators are not always the same person) can confirm this or offer up the correct explanation if mine wasn’t.
So the only issue I have is and fyi I have a lot of pedals. My fuzz pedals sound great with my amps but not so much with the quad which is fine. I can do without them. They just don’t sound fuzzy enough. It could be the amps I’m choosing. I haven’t really fooled around enough with other amps with it yet. Not a big deal. I don’t gif so like I said I just use them with my amps. But I think the quad is great with feel and sound and the UI is great. And it’s nice and compact.
I captured a few lesser known fuzz pedals and shared them on the cloud.
Duality
They’re and Their
Unpleasant Surprise
I don’t think we’re at a point where modeling can quite capture the nuances of a fuzz pedal or the way it reacts, which is unfortunate, because I love me a good fuzz pedal. The QC just isn’t there yet when it comes to fuzz.
Nothing can capture the nuances of fuzz related pedals yet but I think the QC will be able to in the not so distant future.
How not so distant?
Nothing on the radar yet and or announced by NDSP. Keep watching the news on their site for what is coming next

Impedance per scene would probably be fine for all cases but I did wonder more recently if they could leverage the imminent ‘Sidechain’ feature to enable the impedance to be applied on the Fuzz models in particular.
