ML10X feedback issue when trying to use stereo pedal for pre and post

Hey guys,

Having an issue getting my GFI enieqma to work how I want it to. I think I understand there is a feedback loop being created because I am trying to use the stereo pedal as two mono blocks and that somehow messes things up.

What I don’t understand is why it’s happening as it seems the functionality that is built into the pedal by default. It should support a signal being sent on one side and returning on the other. I am hoping to get a pre EQ basically right next to my input block and one post EQ right after a few other blocks before output.

I’ve tried this in advanced mode and that’s where I get the feedback but when I do it in simple it works??? I’m trying to get stereo signal after the EQ shaping from both sides so I was hoping to figure something out.

Any help is appreciated

Do you have the enieqma set to stereo in/stereo-out? (Globals - Routing - Dual Mono)

The other two options mix the two paths inside the pedal, and would create a feedback loop in your setup.

Yeah the setting are stereo in and stereo out, also all three widening settings are turned off/set to zero

I don’t have one, but is there a dual-mono setting separate from a stereo setting? If there’s any bleed from one to the other in a setup like this, you’re going to see feedback. Also, can you take a screenshot of your signal chain in advanced mode? You always have to be careful about feedback in Advanced mode because if a bypassed connection parallel to a non-bypassed connection might cause a feedback loop, as James explains here: [BETA] Engage/Bypass loops in Advanced Mode

I believe this isnt a pedal specific issue, Im sure its just me misunderstanding how to use the ML10X advanced mode.

For the enieqma I am using dual mono/stereo with independant signals for each side

Im reading through that link and the example charts but I’m not entirely understanding why a feedback loop is created. Is the audio signal somehow allowed to flow “in reverse”?

That graph doesn’t have any feedback loops regardless of the bypass states of any block. I think it’s probably the pedal still, but hard to know what exactly.

yeah, if one side is a hot signal and the other one is just a wire, then the hot signal might flow “backwards” as well as forward.

Hm that’s interesting, even in a scenario like the setup I posted would a reverse flow happen to create the feedback? As far as I can tell it’s the same as the routing in simple mode but simple doesn’t have feedback while advanced does

yeah, your current chain shouldn’t be causing any feedback. I noticed you were using a Simplifier (unknown modeal). Do you happen to be using the effects loop on that? I’ve gotten some feedback from my Simplifier Dlx (apparently the signal bleed across L+R channels is intentional, as discussed in this thread: Reddit - Please wait for verification )

Interesting post, but I’ve been able to confirm it’s not on the simplifier side for this specific issue. I cleared my preset and recreated the same exact one as before in advanced and now I have no feedback loop!

Since the chain is exactly the same but before it gave me feedback and now it doesn’t I have to assume this is some sort of phantom connection bug on the editor side where it just wasn’t showing where the feedback loop was created

Sometimes, controller settings might stick, especially after a firmware update, but I haven’t seen it happen for loops. Maybe a loop modification didn’t actually save?

I tried overwriting it multiple times prior to deleting it and starting again from scratch. I guess best practice for modifying a loop is to start from scratch again, which is admittedly slightly inconvenient, though fairly trivial in the grand scheme of things
