Amp Locker vs Amp ONE

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.

Amp ONE is a free iPad application for real-time guitar preamp and cabinet simulation with effects. It turns an iPad into a modeled tube-preamp and cabinet setup, using pretrained artificial neural network models for circuit simulation. Listed preamps include Marshall JCM800, Cornford Harlequin, Engl E530, Krank models, an American hi-gain amp, EVH 5150 III and Fender Blues Junior III. Cabinet power-amplifier behavior is modeled through convolution. Effects include an adjustable noise gate, swell-capable fade timing, four stereo chorus models, delay and reverb. Snapshot and preset functions can save all settings or selected sections. Amp ONE supports AudioBus and Inter-App Audio. The stated requirements are an Apple iPad 2 or later and iOS 7.1 or later; an external audio interface is required to connect a guitar. The App Store listing says it is designed for iPad and is not verified for macOS. Apple’s listing provides no developer privacy details.
