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.

Pro Grid ist um Welten besser!

Allein die Tatsache, dass diese App kostenlos ist reizt zum Testen. Aber das Ergebnis finde ich dürftig (soundmässig!) Die grafische Oberfläche sieht super aus! Das dielt auch für die fix App, die ebenfalls kostenlos ist. Aber die Klangergebnisse können bei weitem nich mit einem Boss Katana mithalten. Die Idee als solche ist gut und wird klanglich auch durch pro Grid, was ich selbst nutze meiner Meinung nach besser umgesetzt.

A public announcement

Ich wäre sehr dankbar wenn Positiv Grid aufhören würde, ihre Bias Apps in eine Werbeplattform zu verwandeln.

Es gibt schon die Mitteilungen von iOS, da braucht es nicht noch die ständige, nicht abschaltbare Mitteilungen in der App. Mindestens eine Opt-Out-Möglichkeit sollte ja wohl drin sein.

Bias Amp 2

Wohlgemerkt, meine Kritik bezieht sich auf das Upgrade auf Version 2, das ich nach kurzen Überblick der Unterschiede zu Version 1 nicht empfehlen kann.
Cannot recommend the upgrade to Version 2
Version 1 is Great, if you own it, leave the upgrade alone. I cannot find any value for the client, but there is in in app purchase of Version 2
If upgrade you are made to believe you get version 2.
you get nothing without paying the hidden in app purchase of the actual upgrade.
In fact you cannot access the important cabinet section any more. It is now greyed out
Looks like another smart attempt to cash in on the idea of Bias without providing any additional value.
Treating clients smart may bring short term gain, but never long term profit.
I like positive grid a lot in the beginning. I like less and less by the day. Not only because I had my experiences with customer care and broken promises.
One star for the upgrade. Disappointing.
