Positive Grid has released version 1.5 of BIAS, a custom app modeler app for iPad.

Insane is one of the new expansion packs for Positive Grid’s BIAS app.

Positive Grid expands the popular custom amp modeler with three new dedicated expansion packs: Glassy, Crunch, and Insane. Guitarists and bassists will now be able to add further customization to their BIAS preamp, power amp, and cabinet modules by tone styles: from glassy clean tone, to classic british crunch, to insanely saturated distortion.

BIAS includes 36 of the most sought-after vintage and modern amps in rock ‘n’ roll history as a starting point for user customization. Now, along with the new Glassy, Crunch, and Insane packs, BIAS also includes a new easy-to-use 8-band EQ with the purchase of any pack, as well as a new BIAS store and better JamUp integration –another Positive Grid app consisting of several multi effect stompboxes-. As always, user can share it with other musicians on Positive Grid’s proprietary social network, ToneCloud.

BIAS for iPad is available for purchase for $19.99 USD. The new in-app expansion packs are $9.99 USD each.
