BIAS starts with stunning replications of 36 of the most sought-after vintage and modern amps in rock ‘n’ roll history and then lets you customize them to respond perfectly to your unique touch and feel. Swap out the tubes, preamp, transformer, tone stacks, cab and mic—even change the tube’s bias—to create your dream amp and distinctive signature sound.
Close your eyes, and you’ll swear you’re hearing the real thing. With BIAS, you 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 meticulously engineered to respond to your playing with immediacy, sensitivity and realism that make you not only sound better but also play better. And BIAS sounds great on bass guitar, too.
But BIAS doesn’t stop there. Create totally new sounds by designing your custom dream amp. It’s as easy as tap and drag. Using BIAS’ highly intuitive and lightning-fast interface, it’s child’s play 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. The result is a depth and range of tones not possible using traditional guitar amps or other modelers. 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, exclusive tones in a heartbeat.

This update fixes tone stack's controls panel mapping issue and "save as" menu issue, and other minor improvements.
This isn't a huge update, but the $4.99 price makes it a no-brainer... if you like guitar apps or have a way to plug your actual guitar into an iDevice. Personally every Guitar instrument app I own eventually gets routed through this awesome piece of sound-good. Not many iOS guitar instruments actually sound nice on their own. Hell, most actual guitars struggle most of the time, thus the need for amps and pedals by the truck load! Bias does as good a job of emulating a real amplifier's sound and feel as anything out there that doesn't weigh 50 lbs. If you've never played electric guitar you might not quite understand that amplifiers really do *feel* when playing through them and it's this response which informs the players energy, style, bravado ... whatever gets your muse on ( as long as it is not getting your 3am dose of MTV through a 100w Marshall stack as an ex-roommate of mine used to enjoy! Amp tone only goes so far... ). Anyway, Bias lets you hook up, choose from bunch of awesome presets and play away. You can tweak the presets, or even design your own amps to a ridiculous degree in the pursuit of sculpting the sound and tone you desire.
Be aware that this is an *amp* simulator not an *effects* app. If you are expecting Flangers and Echoes, your customizations in Bias might seem subtle, especially if you are a user not familiar with the difference between a Fender, a Marshall or a Vox amplifier for example ( there are many others!). The signal path incorporates Equalizers, a Noise Gate and a basic 'Room' ambience effect but it's amp joy all the way and it's all in there to some degree or other. Your amp creations can be opened ... exported really ... to Positive Grid's Jam-Up Pro application which does provide those sonic ear-candy pedals, but it's a separate purchase. Within Bias there are of course, in-app-purchases to expand the amp models avaialable but there's no way they are required. And at the special price you could get the IAP which matches your musical tastes and still spend less than half the amount I did at Bias's release. Though I don't begrudge the developers one cent!
There are different iPhone and iPad versions of Bias so get the one to suit your needs. They even integrate with a Mac desktop App ( purchase required ), though I've never tried it.
If all your iOS-guitars sound limp, then Bias will make things better. If not, check back later and we'll find you a better guitar app.
