Note from Bobby
Note from September 7th 2023
It's very important to note here that this is comparing the Quad Cortex to the Helix Floor and not necessarily other pedals from the Helix series (LT, Effects, Stomp, etc.). This is because I'm comparing size, weight, and touchscreen size. These obviously would be different with smaller pedals in the Helix series.
What are the Differences Between the Neural DSP Quad Cortex and the Line 6 Helix Floor?
Amp profiling, size, effects quality, interface/touchscreen.
These are two very powerful processors with some key differences. Primarily the Quad Cortex is able to capture amps and pedals, like the Kemper Profiler, whereas the Helix can't. The Quad Cortex is also a lot smaller and can actually fit on a pedalboard. We also like the touch-screen interface of the DSP better. That said, the Helix is definitely superior in the area of effects quality. Those are the main differences you should consider when deciding between the two.
| Feature | Neural DSP Quad Cortex | Line 6 Helix |
|---|---|---|
| Pedal Type | Multi-FX, amp modeling, digital amp and effects capture | Multi-FX, amp modeling, rig set up |
| Analog/Digital | Digital | Digital |
| Presets | 10 setlists, 256 presets per setlist | 1024 presets (8 setlists x 32 banks x 4 presets) |
| Number of Effects | 70+ effects | 200+ effects (Helix & Legacy combined, latest firmware) |
| Amp Modeling | 50+ amps, Neural capture technology | Over 100 amp, cab, and mic models (latest firmware) |
| Impulse Response | 1000+ IRs, Third-party IR support | IR support |
| Inputs | Dual combo inputs (TS/TRS/XLR), effects loops, headphone out, MIDI, dual expression inputs, mic preamps | XLR (mic), 1/4" (guitar), 1/4" (aux), 4 x 1/4" (return), RJ45 (Variax) |
| Outputs | XLR, 1/4" TRS, XLR, 1/4" (send), S/PDIF, AES/EBU, L6 Link digital outputs | XLR (L/mono, R), 1/4" (L/mono, R), S/PDIF, AES/EBU, Link out, MIDI Out/Thru |
| USB Connectivity | Audio and MIDI over USB | 8-in/8-out USB audio interface |
| Screen | 7-inch Multi-touch Display | 6.2-inch LCD Display |
| Built-in Looper | Yes | Yes (60 seconds mono, 30 seconds stereo) |
| Expression Pedal | Yes (dual expression inputs) | Built-in pedal |
| Wi-Fi Connectivity | Yes (firmware updates, preset sharing, cloud backups) | No |
| Construction | Aluminum housing, 1.8mm glass display shield, solid construction | Solid-aluminum construction, tour-grade footswitches |
| Weight | 4.2 lbs. | 14.6 lbs. |
| Dimensions (HxWxD) | 2" x 11.4" x 7" | 3.61" x 22.05" x 11.87" |
A larger touchscreen, yet with a smaller pedal form wins out in my opinion, even though the Helix is superior in the effects quality department. Image via Chriswangtastic
The Helix is really big, making room for an expression pedal and functions as its own pedalboard. Though keep in mind, there are smaller versions like the Helix LT and HX Effects. Image via Live Rig Share
Top 10 Notable Differences
- Amp and Effect Models: The Quad Cortex offers over 50 amps, 70+ effects, and 1000+ IRs, while the Helix has over 100 amp, cab, and mic models, along with 200+ effects.
- Presets: The Helix has 1024 presets (8 setlists with 32 banks x 4 presets) compared to Quad Cortex's 2560 presets (10 setlists with 256 presets per setlist).
- Expression Pedal: The Helix has a built-in expression pedal, whereas the Quad Cortex supports dual external expression inputs. However, the Helix supports multiple external expression pedals as well.
- USB Connectivity: The Helix serves as an 8-in/8-out USB audio interface for recording and a computer connection, while the Quad Cortex focuses on audio and MIDI over USB with a mobile app (more on that below).
- Screen Size: The Helix features a slightly smaller 6.2-inch LCD display, while the Quad Cortex has a 7-inch multi-touch screen that responds really smoothly, similar to an iPhone.
- Looper: Both processors have built-in loopers, but the Quad Cortex offers a longer recording time (up to 4 minutes and 44 seconds) compared to the Helix (60 seconds mono, 30 seconds stereo).
- Wi-Fi Connectivity: The Quad Cortex has Wi-Fi for firmware updates, preset sharing, and cloud backups/sharing, while the Helix lacks Wi-Fi functionality.
- Software: The Quad Cortex has a mobile app (Neural CNS Mobile app), but most of the functionality is onboard and can connect to a cloud account via Wi-Fi. The Helix can connect to a computer via USB and has a full, deep editing software solution, which - in our opinion - is the preferable setup.
- Weight: The Quad Cortex is significantly lighter at 4.2 lbs, making it more portable, whereas the Helix weighs 14.6 lbs.
- Size: The Quad Cortex has a more compact design, making it easier to transport and include on a pedalboard, whereas the Helix is larger and functions as its own pedalboard.
What would I go with?
Of these two, I would probably go with the Quad Cortex for a few reasons. Frankly, the size is just a huge issue for me when it comes to the Helix Floor. The thing is just huge, so I'd much prefer something that fits on my pedalboard, especially since the Quad Cortex has a bigger touchscreen.
As I mentioned in the top box, this does not necessarily apply to other versions of the Helix. It just depends on which one you're comparing.

The amp and pedal capturing is also a solid feature, similar to what you can do with the Kemper Profiler. And while the effects on the Helix are better quality, I'd personally rather have the nicer touchscreen and the smaller unit.
As always, your context is the more important consideration.
