Amp ONE review
A free iPad amp-and-effects app for guitar practice, presets, and mobile audio workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Amp ONE is a free iPad guitar amp and effects application from Mercuriall Audio Software. It is aimed at guitarists who want amp-style processing and practice effects in an iPad-based setup. The signal chain includes circuit-based guitar preamp simulation, cabinet simulation using convolution and impulse responses, a noise gate, four stereo chorus models, delay, and reverb. For saving sounds, the app provides presets for selected-section settings and snapshots for complete settings.
The free plan keeps the product straightforward: it includes the iPad guitar amp and effects application without a paid tier structure described here. Its strongest fit is for players who want core amp and effects processing without a purchase, especially when preset recall and full-setting snapshots are useful. The noise gate offers adjustable threshold, attack, release, and fade timing, giving users more control over how unwanted signal is managed. Cabinet processing is handled through convolution and impulse responses, while the preamp is presented as circuit-based simulation.
Amp ONE also fits iPad audio workflows through Audiobus and Inter-App Audio support. Real-time playing is supported through an external audio interface, so the practical setup centers on an iPad, guitar, and compatible interface. That makes it a focused choice for mobile practice and effects processing rather than a broad desktop production environment. Choose Amp ONE if free iPad access, amp-and-effects essentials, and snapshot-based recall match your workflow. Choose another option if you need a desktop platform or a wider verified range of processing tools.
