6 more amps, any two effects at once, more user presets, and best of all you can upgrade the old Catalyst to CX with a firmware update!

Catalyst 2.01 (released March 19, 2024) includes six additional amp models derived from our Helix® family of processors, along with the ability to use any two of the 24 on-board effects at a time. There are also some improvements in how you access the different effects, and new visual cues for the different amp functions.

How do I update to 2.01?
Go to, click on "Downloads", and install Line6 Central to your computer. This is an application that will facilitate this and future updates.
Connect your Catalyst or Catalyst CX 60, 100, or 200 amplifier to your computer and launch Line 6 Central.
Log in with your Line 6 credentials (or create a new account if you don't have one). The software will walk you through the entire procedure for updating the firmware.
Power on the Catalyst or Catalyst CX amplifier with the master volume all the way down.
The screen will show your product and which version of the firmware is currently loaded. It will also say "UPDATE AVAILABLE"
Clicking on the amp image will take you to the Update page.
Click on "PERFORM UPDATE" and accept the terms and conditions.
You will receive a message that your amp is restarting in Update Mode.
When the update is successful, you will see a message like this:
Click OK and you are complete!

Bug Fix - (for Catalyst CX users only)
In Firmware 2.0 (the factory default firmware for Catalyst CX), If the CLEAN AMP in group 2 is selected, there is audible hum which is part of the model default. Updating to 2.01 firmware will eliminate the issue.
Compatible OS: Mac OS X, Windows 7, Windows 8, Mac OS Mavericks, Mac OS Yosemite, Windows 10, Mac OS El Capitan, macOS Sierra, macOS High Sierra, macOS Mojave, macOS Catalina, macOS Big Sur, macOS Monterey, Windows 11, macOS Ventura


What is Catalyst CX?

The CatalystT® CX family of combo amplifiers represents both a physical update to the original Catalyst family, as well as a firmware update.


What does the new Firmware offer?

·        Catalyst CX doubles the number of amp voicings to 12 (compared to the 6 in the original Catalyst) and includes many of our Original Amp Designs—ranging from pristine clean to modern high-gain—with all amp models derived from the Helix® family of amp and effect processors.

·        Catalyst CX allows for the use of simultaneous effects (Boost, Effect 1, Effect 2)

·        The effect selection process has been simplified, with the "audition" time for selecting effects extended. 

·        Added visual cues to identify when you enter/exit Effect selection mode, Preset Bank selection, and more.

·        Additional default deep-parameter settings optimize each amp voicing when in MANUAL mode.

·        Expanded functionality of the optional LFS2 footswitch (accessed through the free Catalyst Edit software).

·        Updates to Catalyst Edit software to capture the new firmware functionality.


What are the physical differences?

·        A new custom black & tan grille cloth provides a more traditional look.

·        Subtle two-tone piping (cream with an enclosed gold braid) outlines the grille cloth, adding to the "boutique" design style.

·        Updated silk art on the control panel is designed to enhance the user experience by calling out some of the key updates related to the 2.01 firmware.


What amps and effects are included?

The amps in Catalyst CX are split into 2 groups of 6: the 6 original Catalyst amps are in group 1, and 6 NEW amps are in group 2. You can switch between them by pressing the Ch A and Ch B buttons simultaneously:

·        Boosts—Just like the original Catalyst, there is a customized boost to match each of the 12 amp voicings


·        All of the original 24 Effects from Catalyst are present, and now can be accessed any 2 at a time. (also all taken from the Helix family of products)



* PLUS a Built-in adjustable Noise Gate


Can I edit them beyond just effect mix?

Yes, deep editing of effects is available in Catalyst Edit, available FREE on macOS, Windows, iPhone, iPad, and Android devices.


 Does it take pedals well?

Absolutely – external effects can be placed in front of the amp input, in the effects loop, or run an external modeler into the power amp in jack.


Are there presets like other Line 6 products?

Catalyst stores 6 banks of presets with 2 channels each, for a total of 12 presets.  Presets can also be edited/saved using Catalyst Edit software.


I have the original Catalyst amp. What about me?

All of the new firmware features (new amps, and more) are available to ALL original Catalyst amp owners as a free download (Firmware 2.01) HERE:


Is there a Footswitch for Catalyst CX?

Yes, the Catalyst & Catalyst CX amps have a standard ¼" input for the optional LFS2 footswitch.

The 2-button LFS2 is a roadworthy metal latching footswitch that provides stock control of Channel and Effect on/off status, while both footswitches may be reassigned via the Catalyst Edit app to control a number of other functions, including Boost on/off, Reverb on/off, Tap Tempo and more. A ten-foot/3.3m right-angle/straight TRS cable is included.


When is Catalyst CX shipping?

March 2024, worldwide.


Where can I learn more?



-      Currently, there is an issue with disabling the Cab simulation on the direct output within Catalyst Edit. We encourage users to leave cab sim enabled on. The issue is being evaluated for update in a future release.



I found out about this today when I saw there was an update to the Android app... the first proper update since it was launched two years ago. Nice to see that they haven't forgotten the Catalyst. I'll test this tonight – I really hope the app has been improved as currently it just crashes continually every time you try to save a change via Bluetooth.

the ability to run two effects is very welcome. It would have been nice to have more options on the footswitch – i.e. assign each button to an effect or the effect loop etc.

I wonder if we'll see an amp that build on the HX One – choose one amp model and two effects from the Helix range etc.

Catalyst lacks any Bluetooth/BLE connectivity

All Catalyst Editors, All Platforms require a wired USB Connection
It does not employ MIDI for the Catalyst editor so no support for  CME WIDI USB  wireless.

I use Android and a USB  cable - never have any crash

Read the Catayst  Editor Requirements for Android

• Connects to Catalyst Amplifiers via USB

I use this cable and I can connect to the Catalyst Editor with my Samsung Android phones with USB-C - and instantly have a USB Audio connection from my Android phone or iPad Pro  - all apps with audio route to the Catalyst Amp , and I can hear 24bit stereo audio from Catalyst Headphone jack or 200 watts mono on Catalyst Speakers

For iphone/iPad IOS devices with Lightning ports

Use this cable
