BIAS AMP 2 Mobile is a professional virtual amp designer that offers replications of 36 of the best vintage, modern and boutique amps in rock. The app gives you the power to create new sounds by designing your own dream amplifier, letting you swap out tubes, preamps, power amps, transformers, tone stacks, cab, and microphones, all via a powerful and intuitive interface designed for your iPad. Whether you’re a classic rocker, metalhead, jazz player, bluesman or singer-songwriter - and whether you understand how amplifier electronics work or not - you’ll be dialing in killer and exclusive tones in a heartbeat.

BIAS AMP 2 Mobile adds a host of new features, including a powerful new user interface, new preamp and power amp modules, tubes, tone stacks, Blues and Bass amp packs, new Dynamic Tone Control, new speaker cabinet module with multi-mic capability and open/closed back cabinet emulation and much more. In addition to all of these amazing new features, we’ve also partnered with legendary Celestion to create brand new custom multi-mic speaker cabs using their famed impulse responses! (Additional preamp, power amp and cab models are available via in-app purchase)

BIAS AMP 2 Mobile seamlessly integrates with Positive Grid’s ToneCloud®, which is far more than a simple storage tank for your own custom tones - it’s an active community where thousands of guitarists upload, share and discuss tones. The ToneCloud® gives you access to thousands of custom amps created by artists, recording studios and guitarists like you, so you’ll never lack for sonic inspiration.

To take your tones to the next level, there are 9 full-featured reverbs in BIAS AMP 2 Mobile. These aren’t just simple two-knob reverbs either - they range from lush halls and chambers to intimate rooms, and each reverb has control of decay time, mix level, high and low cut filters, damping and dwell.

BIAS AMP 2 Mobile integrates seamlessly with Positive Grid's BIAS FX and JamUp guitar multi-effects apps for iPad, expanding BIAS AMP 2 Mobile into a powerful and completely unified professional guitar system for live use, recording and jamming. Both JamUp and JamUp Pro include effects processors, Jam player, 8-track recorder and phrase sampler, tuner and metronome, effectively turning BIAS AMP 2 Mobile into a recording studio and top-of-the-line practice utility.

BIAS AMP 2 Mobile also works with GarageBand and other audio apps using iOS’s Inter-App Audio and Audiobus. Whether you’re recording, writing songs or honing your chops—at home or on the road—BIAS products place unequaled tone at your fingertips.

Le meilleur simulateur d’amplis

De loin la meilleure application de ce type. Couplé à Bias FX, un choix infini de sons s’offre à vous.

La version desktop est encore plus performante (pour les amateurs avertis de home-studio car plus onéreuse). Sur la version desktop, Amp Match est assez bluffant : vous pouvez recréer un ampli par capture audio. Je peux assurer que le résultat est fidèle si, en plus du résultat de l’algorithme, vous ajoutez quelques réglages à l’oreille. Un must !

La version 2 de cette application la rend encore plus performante et offre un choix encore plus grand de composants pour créer les amplis qui vous correspondent. Les bassistes se sentiront aussi mieux équipés et représentés qu’auparavant.

Les bugs qui peuvent parfois apparaître lors de mises à jour sont rapidement résolus du fait d’une team à l’écoute de leurs consommateurs.

Indispensable pour les musiciens soucieux de qualité

Pas de restauration des achats iPad vers iPhone!?

Bias Fx en revanche gère parfaitement, avec en plus la possibilité de sauvegarder ses presets sur Dropbox. Je ne comprend pas pourquoi Bias Amp 2 ne bénéficie pas des mêmes avantages.
Dommage pour une App que j’apprécie beaucoup.

Mise à jour Capricieuse

Possédant la Bias head, cette mise à jour plante dès que je sélectionne un ampli en façade.
Jamais eu ce soucis avec la v1.
J’espère que positive grid va rapidement corrigé ce bug qui rend inexploitable le soft avec l’iPad.
