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 iPhone. 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 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 app, 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.

Purtroppo ogni 30secondi c’è un disturbo(come una scarica) che si ripete e non si può ingnorare. Se risolvete vale sicuramente 5 stelle! (iPhone 12mini + basso fretless + iRig + cuffie)

Be aware you have to buy bundles twice (pay real money two times) between iPad and iPhone

I bought bias amp 2.0 unlock and another bundles on my iPad and was really ready to buy more, right before that I decide to pick up my iPhone to check it up there and my iPhone (same Apple ID and all on both devices) won’t allow me to use the content I have to buy it again? Really you guys need to be more specific with this kind of matters, having to buy your products between iPad iPhone twice is not the best customer reward... is already bad enough you have to pay for the macOS version but I kind of understand, different OS after all, between iPhone and iPad absolutely not.

Hi, BIAS Amp 2 iPhone is a universal app, but BIAS Amp 2 iPad isn't. If you need to transfer your purchases to iPad, please make sure you install the iPhone version as well. Thank you for your feedback.

Ho speso male i miei soldi

Ho comprato con il mio iPad la prima versione di bias amp,
Poi la secondo(bias amp2).
Quando decido di scaricare bias amp 2 sul mio iPhone scopro che tutti i miei acquisti non sono validi.
Cosa pretendono che riacquisti tutto per la seconda volta??
P.s: con bias Fx tutto quello che ho acquistato con iPad lo ritrovo anche su iPhone
