Conventional Guitar Amp with Modern Versatility

Marrying 12 diverse amp voicings and 24 comprehensive FX from the celebrated Helix processor with a compact and versatile combo amp design, the Catalyst CX 100 from Line 6 is a 100W 1x12" modeling guitar amp ideal for band rehearsals, practice, and moderately large stages.

12 Amp Voicings

Select one of 12 amp voicings derived from the Helix amp and effects processor. From pristine clean to modern high gain, you can achieve a wide range of amp tones with a simple turn of a knob.

Traditional Controls, Plus More

Catalyst CX amps feature familiar Volume, Gain, Tone, and Reverb controls, plus numerous effects and other options under the hood.


  • Three-band EQ control
  • Presence control
  • Adjustable gain boost circuit, with boosts optimized for each amp model
  • Gain boost doubles as a gate control when activated
  • Channel selection plus manual mode
  • Individual channel volume control
  • Separate preamp and master gain control for ideal distortion in any environment
  • Selectable power levels, from 100 down to 0.5W

Onboard FX

Select up to two simultaneous FX at a time, and choose from 24 different reverb, delay, modulation, and pitch effects, all derived from the Helix processor. Each FX channel offers adjustable levels and pre/post control.

Tempo and Tuning

Tap in the tempo when using time-based effects, such as delay and tremolo. Press and momentarily hold the button to access the handy chromatic tuner.

Output Power

With the Output Power selector knob, you can reduce power from 100W down to half power (50W), 0.5W, and a Mute option. With the Mute, you can completely silence the speaker, using only the preamp and modeling hardware, ideal for DI recording or sending your signal to an external PA or cabinet.

Power Amp Input and FX Loop

Use the Catalyst CX as a powered speaker by bypassing the preamp. Perfect for use with amp modelers and simulators, this option is available after flipping the Mode switch next to the FX return jack from FX Loop to Power Amp In.

USB and MIDI

With the built-in USB-B connection, you can connect to the Catalyst Edit app (macOS, Windows, iOS, and Android) and to the onboard audio interface, which provides four channels at 24-bit and either 44.1 or 48 kHz. Catalyst CX 100 also sports a 5-pin DIN input for direct MIDI connections from interfaces, processors, and other gear.
