Amp Locker vs Helix Stadium Native

Amp Locker is a guitar sound-shaping suite built around virtual amps, stompboxes, cabinets, and effects. It runs on Windows, macOS, and Linux as a standalone app or plug-in. The free download includes the Prestige 1950 amp, seven FX pedals, seven rack effects, and 11 three-dimensional cabinets with 11 microphones. Users can adjust pedals and rack effects and move microphones around the cabinets. Other listed tools include double tracking emulation, MIDI support, an IR loader, and the 3D Cab Impact algorithm. The stated plug-in formats are AU, VST3, RTAS, and AAX. More gear modules can be licensed individually inside the application, and optional extras include DSP and AI amp profile players. The $5 a month subscription covers Amp Locker and Mix Locker modules, but excludes 3D Cab add-on packs and signature amp sims such as Berry Amp. Cancelling the subscription deactivates the plug-in. The license limits installation to machines where the licensee is the sole user and bars machines that could redistribute plug-ins to other computers.

Helix Stadium Native is an amp and effects plugin that brings Helix Stadium hardware sounds and tone tools into a digital audio workstation. It runs on macOS and Windows in AAX, AU, and VST3 formats, and is not a standalone app. The product page lists 132 amplifier models with 152 channels, more than 260 effects models, and more than 60 speaker cabinet models. The full license lists 27 Agoura amps with 55 channels plus 111 HX amps, 46 cabinets, and 274 studio effects. Hype control blends between more authentic and idealized amp sounds, while Focus View provides contextual parameter controls. The plugin supports third-party cabinet impulse responses and Proxy clones, as well as presets and setlists from Helix Stadium and Helix Stadium XL and original Helix and HX products with firmware 3.50 or later. External MIDI controllers and software can control parameters and snapshots. A free Intro plan is available; the full license costs $399.99 as a one-time purchase purchase and includes a 15-day trial.
