Positive Grid has announced the launch of BIAS, a complete, accurate and versatile guitar amplifier modeler and designer that is equipped with 36 replications of rock ‘n’ roll history’s most sought-after vintage and modern amps.

“Ask any guitarist what’s most important in a guitar amp app, and you’ll get the same answer: great tone,” says BIAS product manager Calvin Abel. “We didn’t think we’d be pushing the boundary by merely adding more bells and whistles to an amp simulator, so we threw out convention and focused instead on how to create the most delicious tone in as many flavors as possible.

“The result is BIAS, which allows guitarists to change preamp tube types, edit preamp voicing, adjust bias, audition various transformer types, swap out loudspeakers and cabinets, move microphone placement and much, much more. Never before have guitarists had such a broad palette to create their own dream amps and distinctive signature sounds.”

With BIAS, guitarists own a complete virtual collection of the most coveted and unique guitar amps of all time—some dating as far back as the 1940s. Every amp model is engineered to respond to playing with immediacy, sensitivity and realism, helping guitarists not only sound better but play better as well. And BIAS works well with bass guitar as well.

The intuitive and fast interface makes it simple to instantly swap out colorful tube preamps, lush distortion circuits, classic tone stacks, boutique power stages, custom-built transformers and cabs loaded with specially matched speakers.

BIAS also integrates with other audio apps to provide a complete music production environment. Open amp models with one tap in JamUp Pro XT, Positive Grid’s powerhouse multi-effects processor, 8-track recorder and phrase sampler for guitar and bass. Or use it with Apple GarageBand and a myriad of other audio apps using iOS7’s Inter-App Audio and Audiobus.

BIAS retails for $19.99 and is available for download at the iTunes App Store here. Designed for iOS7, it requires an iPad 2 or newer to operate.
