Amp ONE vs Soundshed Guitar

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.

Soundshed Guitar is a free guitar and bass multi-effects app for Windows, macOS, and Linux. It runs standalone or in a DAW through VST3, AU, or CLAP. Neural Amp Modeler A2 supplies amp tones, with Tone3000 available inside the app. Effects can be arranged in any order, split into parallel paths, connected through graph-based routing, and combined with other plugins. Impulse-response cabinet simulation lets users load and blend their own cabinets. Community presets and tone packs can be browsed, complete setups imported, and preset assets transferred between systems or collaborators. Built-in tools include a tuner, metronome, jam backing tracks, quick riff capture, and a Practice Tool. Version 1.6.0 adds nine effects, fifteen drive pedal models, gapless preset switching, signal-chain undo, and A/B comparison. Minimums include Windows 10/11 x64 with AVX2, macOS 11+, 4GB RAM, and 500MB disk space. Listed audio rates are 44.1–96kHz with latency under 10ms at 48kHz.
