Positive Grid has introduced BIAS, a new app that they say turns your iPad into “the world’s most complete, accurate and versatile guitar amplifier modeler for iPad”.

BIAS starts with replications of 36 of the most sought-after vintage and modern amps and then lets you customize them. Swap out the tubes, preamp, transformer, tone stacks, cab and mic – even change the tube’s bias.

Here’s a demo of BIAS in action:

Features:

  • 36 amp models included with the introductory release
  • Factory categories organize amps by music genre and sonic impact: clean, blues, twang, crunch, metal, acoustic and bass
  • Fully customizable preamps, tone stacks, power amps, transformers, cabinets and mic selection and placement – mix and match
  • Customize the look and feel of your own amp panel, change name, tolex, panel and knobs.
  • Works the way guitarists think: tweak gain and overdrive, swap out tubes and transformers, change the cabinet and mic position, and shape the tone with different tone stacks and two 8-band equalizers
  • Included noise gate and room simulator
  • Create a virtually unlimited number of custom amps
  • Quick preset to recall each of your 8 favorite settings in turn with just one tap
  • Seamless integration with JamUp XT and JamUp Pro XT, open and save your amp models inside JamUp with one tap

  1. Slick GUI. Sounds pretty good. Looks like it has lots of tweak-ability.

    On one hand, if $20 is all inclusive and doesn’t get into IAPs, that’s a plus. On the other hand, with so many guitarists in the world, think how many more licenses they’d sell at $10. But I guess they’ve done their market research.

    I’d be curious to hear what tone-snobs think of this as compared to the other big amp sims.

    • If you were a ‘tone snob’ I imagine you’d dismiss this pretty rapidly along with the rest of the gimmicky junk.. Either way, if I wanted to take my guitar mobile THAT badly I’d build a Smokey amp for a quarter the price of this.

  2. I wonder what sort of algorithm they use for emulating vacuum tubes and how they distort, because a simple distortion with solid state or programming is just to have it clip the fuck over the audio signal, but if you want a more proper emulation you’d need something cleverer. Anyway, it seems like a rad app, if I had an iOS device I’d definitely buy it.

  3. BIAS is a great way for beginners to learn what they need to regarding amps. Also, not everybody can afford buying different amps, and this app makes jamming it up easy and available for everyone. Playing around with the different tones and effects helps you build your knowledge and helps you narrow down your music genre you prefer to play.
