Catalyst Integration
The six Catalyst-based amp models (Clarity, Aristocrat, Carillon, Voltage, Kinetic, Oblivion) bring the tube-amp-like characteristics of Line 6’s Catalyst amplifier series into the Helix platform. Each model includes an integrated boost circuit, providing two tonal characters per model. These additions fill important gaps in the Helix amp roster and give players access to tones that were previously exclusive to the standalone Catalyst amplifiers.
Who Benefits From This Update
Every owner of a Helix or HX device benefits from this free update. The new amp models expand tonal options, the cabinet captures add authentic speaker response options, and the new effects algorithms provide fresh creative tools. The bass amp and cabinet additions are particularly welcome for low-end players using Helix as their primary rig.
Who Should Buy the Line 6 Helix Firmware 3.70 Update
This update is a must for all Helix, Helix LT, HX Stomp, and HX Effects owners. Firmware 3.70 brings Catalyst amp models into the HX ecosystem along with 10 new amp models, significantly expanding the platform’s tonal range. If you’ve been eyeing the Catalyst series tones but prefer the Helix form factor, this update gives you the best of both worlds. It’s free, adds real value, and keeps the Helix platform competitive with newer units on the market.
