Amp ONE vs Amp Room

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.

Amp Room is Softube’s guitar and bass platform for building tones from modeled amplifiers, cabinets, pedals, microphones, and studio effects. Five suites cover ENGL Savage Mark II, Marshall, Vintage, Bass, and Metal, with different gear combinations in each. Officially licensed effects come from Tube-Tech, Empirical Labs, Trident, and other makers. Suite Mode presents selected gear sets, while Studio Mode allows further tone shaping. Suite listings include a custom impulse-response loader, eight IR Producer Packs, customizable signal chains, and cabinet captures with movable microphones. Suites can be expanded with other Amp Room Suites and Amp Room Ready products. The software runs as AU, VST, VST3, or AAX inside a compatible DAW on macOS or Windows; it is not standalone. Use requires Softube and iLok accounts plus internet access. Prices range from €99, paid once to €149, paid once, with a 20-day trial.
