So guys, Bias is announced by PositiveGrid.
The app is amazing, really a breakthrough in amp emulation. Bias kind of put Amplitube Desktop into the archive regarding flexibility and possibilities. And the tone is open, clear, real tube breakup.
Here is a screen shot of "my" amp which is based on the Hiwatt 103. But I've changed the internals.

This picture is taken from an early build which had only guitar gear.
But, don't worried bass amps will be available. You know some of the models, but now they will sound better and you will be able to look and adjust the internals!
