## Description

BIAS AMP 2 Mobile is a professional virtual amp designer that lets you dial your own tones by swapping tubes, preamps, power amps, transformers, cabinets, and mics — all through an intuitive iPhone interface. It ships with 36 amp models at launch and gives access to thousands more via ToneCloud, with organized factory categories for clean, blues, crunch, metal, bass, and more.

New features include a redesigned UI, expanded tube options, Blues and Bass amp packs, Dynamic Tone Control, a multi-mic speaker cabinet with open/closed back emulation, and Celestion custom multi-mic cabs. BIAS AMP 2 Mobile integrates with BIAS FX, JamUp/JamUp Pro, GarageBand, Inter-App Audio and Audiobus to create a unified guitar system for live performance, recording, and jamming. Optional in-app purchases unlock additional amps, preamps, and cabs.

## Review summary

Bias Amp 2 for iPhone offers excellent tone and real-amp feel when it runs well, but users repeatedly report instability, compatibility hurdles with OS/app ecosystems, and a painful cross-device purchasing model. The core sounds are strong and educational, yet reliability and pricing consistency across devices remain major concerns.

### Pros

- Great sounding amp sims with high-quality tones.
- Moddable, flexible interface that mimics a real amp.
- Strong for live use and direct recording through a PA or console.
- Valuable learning tool for recreating tones and training your ear.

### Cons

- Frequent instability and crashes, with static/noise and dropped or broken audio on many devices.
- Compatibility and integration issues across iOS versions and hardware (GarageBand/Cubasis inter-app audio, AUv3 support, iRig2 quirks).
- Double purchases for updates across iPhone and iPad, with purchases often not syncing or clearly communicated.
- Device- and OS-specific audio distortion or irregular performance on some devices.
