Has QC come of age for clean and edge tones?

Hello, it’s that time of the years again when I revisit QC to determine whether it has come of age. I was an earlier adopter with QC, but I was so unimpressed with the clean and edge of breakup tones that I took the view that Neural DSP was all about long bearded Scandinavian Strandberg-weilding guitarists (who are all jolly good chaps…) and really weren’t so focussed on the clean side of tones, and to be fair their plug-ins (although excellent) reflected that too … the feel under the fingers was simply no better than my Atomic AF12 at the time and I returned it, but that was two years ago, and since then I have used Strymon Iridium which personally I find is the best digital modeller for clean to classic rock, but obviously you end up with a clunky pedalboard.

So what’s QC like now? I read there been significant improvements. What I want to hear is really from players who have used Strymon Iridium and then bought a QC. Does it ‘feel’ like an amp at clean and edge tones?

I don’t understand your post. The QC can do it all. I’ve captured several amps each with numerous gain/tone settings and the QC produces these pretty much perfectly. It doesn’t have a preset tone or limitation. It is merely cloning what the output response is for a given input.
My live presets include clean, slight crunch (just starting to clip), full crunch, OD and metal. I’ve performed about 150 live gigs with my QC and still absolutely love it and often get comments about my tone. Patrons are shocked at how good I sound without a guitar amp. And I most definitely produce excellent clean and edge tones.


If you didn’t like it before, you won’t like it now. It’s fundamentally the same unit.

“Feel” is subjective and very hard to quantify. That aspect of the QC has not changed. It feels and sounds the same as ever.

However, that sound is pretty great. I only use clean and EOB tones and have never been disappointed.

I came from the Strymon Iridium and although it’s a great little unit the QC can do SO much more. How you monitor or amplify the QC is a huge part of the equation and basically by nature it will sound or feel like a recorded “amp in ANOTHER room,” not an amp in the same room- it’s a different experience and application. Running it into a power amp and cab may get you closer to that if that’s what you’re looking for


Hey there,
It’s intriguing to revisit the Quad Cortex (QC) and assess its progress, particularly in delivering clean and edge-of-breakup tones. Your past experiences with gear like Neural DSP and Strymon Iridium offer valuable insights into what you’re looking for in terms of tone and feel.
While I haven’t personally transitioned from the Strymon Iridium to the QC, I’ve heard from fellow guitarists who have made the switch and found the QC’s improvements to be quite notable. The advancements in modeling technology seem to have addressed many of the previous concerns, offering better emulations of amp characteristics, including cleaner tones and nuanced edge-of-breakup textures.

Thanks Manny, someone’s understood my point, have the core cleans and EOBU tones improved or is the unit and tones (as someone suggests) the same … I can’t believe they would still be developing this just for the high gain merchants… I guess the only way is to buy one, check it out and return it if it doesn’t make par. Thanks again!

The sounds are the same.


QC Always ready for beautiful clean and Edge clean tones.


It’s always been great for cleans and EOB. I imagine it’s quiet in this thread because no one really agrees with what you’re saying…

If you want it to feel like an amp, you need to pair it with a big amp (no shit) and a proper cab. If you pair it with an anaemic little SS pedal, it’s not going to perform like a 100W valve amp.

It’s not a question disagreeing, I was simply after was someone who had the same journey as me … didn’t happen… so I’ve ordered one and we’ll see, I can compare it vs real Boogie, and TKI, and if it really is as good as you all claim then great, if not end of.

As was mentioned previously, mic your boogie in another room run it through some Pre’s, a DAW, and listen through monitors. A QC will knock your socks off with how accurately it will replicate that tone.

Plugging your QC in and listening through headphones, vs standing 3 feet from your cranked boogie is an apples/oranges.

But to answer your initial question/post there are some really incredible clean/ EOB captures in cortex cloud and the rest of the ether.


well, I mean- I did…

dialing it in is going to be the responsibility of the user and will depend on all the other elements of the signal chain, especially regarding monitoring.
If you had one before and didn’t like it, don’t expect to this time either if you’re setting it up the exact same way.
