Amp ONE
Amp ONE is a free iPad app for real-time guitar preamp and cabinet simulation with effects.
What Amp ONE is
Amp ONE is a free iPad app for real-time guitar preamp and cabinet simulation with effects. It uses pretrained artificial neural network models for circuit simulations, and models the power amp stage as part of the guitar cabinet through convolution. Listed preamp circuits include Marshall JCM800, Cornford Harlequin, Engl E530, Krank Krankenstein and Revolution, an American hi-gain amp, EVH 5150 III, and Fender Blues Junior III. Effects include a noise gate with adjustable opening and closing thresholds, attack and release, and fade timings that can create a swell effect. Four chorus models are listed, along with delay and reverb. Snapshot and preset systems can save and restore all settings or selected sections. The maker lists AudioBus and Inter-App Audio support. Connecting a guitar to the iPad requires an external audio interface. Stated requirements are Apple iPad 2 or later and iOS 7.1 or later. The App Store describes the app as designed for iPad and not verified for macOS; its listing also says the developer has not provided privacy-practice and data-handling details.
Good
- Includes models of several named preamp circuits.
- Offers four chorus models, plus delay and reverb.
- Presets can save all settings or selected sections.
- Supports AudioBus and Inter-App Audio.
Watch out
- Requires an external audio interface for guitar connection.
- Designed for iPad, not verified for macOS.
- Requires iOS 7.1 or later and iPad 2 or later.
- The developer has not provided privacy-practice details.
Who it suits
Amp ONE suits guitarists who want to play through modeled amplification and effects on an iPad. It requires an external audio interface to connect a guitar.
Verdict
Amp ONE offers modeled preamps, cabinet simulation, and several effects in an iPad app. Confirm that your iPad meets the stated requirements and that you have an external audio interface for connecting a guitar.
