Virtual Amp Designer

Your tone is your identity and sometimes nothing less than a custom setup can deliver the goods.

Create authentic and mind-blowing tones that can be tweaked and fully customized.

BIAS AMP 2 is the ultimate virtual amp designer, authentically recreating the tone and feel of real tube amplifiers, while allowing you to mix and match components to create your ideal amp. You can use Amp Match to clone the tone of real hardware or a guitar track, or connect to the ToneCloud® to gain access to thousands of custom amps from artists and recording studios, or upload your own custom tones to the cloud. 

BIAS AMP 2 represents a revolution in virtual amplifier design, providing the tools to take your ultimate guitar tone with you anywhere, from the studio to the stage and back again.

What's New in Bias Amp 2 - Create the Amp of Your Dreams

Dynamic Tone Engine

For BIAS AMP 2 we worked with artists, engineers and recording studios to improve the already hyper-authentic touch response of our amplifier circuits. The result is a new playing experience, with increased touch responsiveness and dynamics. With new tubes, transformer, dynamic tone control and a completely redesigned speaker cabinet module with multi-mic capability, you now have the tools to take your tone explorations further than ever before!

Bias Meets Celestion

When it comes to speakers, Celestion is the most trusted name in the history of rock and roll. Their drivers have been used on more classic songs and tones than any other manufacturer, and their impulse responses are the favourites of guitarists ranging from Pete Thorn and Scott Henderson to George Lynch. We’ve partnered with Celestion to make their IR’s easier to use than ever before, so you can forget loading individual files! Just select a custom Celestion cab and start moving the mics around – BIAS AMP 2 does the rest.

Redesigned Amp Packs

Along with BIAS AMP’s built-in amp packs, BIAS AMP 2 adds two new amp packs that widen the sonic palette even further. Blues is all about gooey clean to mid-gain amps, and Bass brings amps and speaker cabs just for bass guitars. Add in all of the custom component options, and you have literally thousands of custom amps at your fingertips. There’s nothing else like it!



Lush Reverbs

BIAS AMP 2 also includes nine built-in reverbs, ranging from huge halls to intimate rooms with full control over the character of the reverbs. Between the different reverb types and the extensive filtering and saturation options, BIAS AMP 2 has all your reverb needs covered.

New Amp Match

AMP Match can already match the tone of any mic’d reference amp, but we’ve made it even better in BIAS AMP 2: now matching a tone is as easy as importing an audio file! Not only that, if you aren’t all that familiar with dialing amps yourself you can ask AMP Match to guess the circuit for you. You’ll get faster and better results no matter what your skill level is, making it even easier to get to your ideal tone.

Enhanced Authenticity

AMP Match utilizes a collection of underlying technologies to analyze and compare your currently selected BIAS amp model and the sound of a target tube amplifier, including the speaker cabinet and microphone. It then executes the tonal compensation and enhancements needed to make your amp model’s sound accurately match that of the target tube amplifier.

100 Amp Match Presets - Don't Sweat the Details

Even if you’re not interested in matching amps yourself, you can still take advantage of the power of AMP Match by connecting to the Positive Grid ToneCloud and enjoy 100 new custom AMP Match presets. There are thousands more from artists, recording studios and guitarists from around the world.

What’s New In Detail

New Tubes and Amp Packs

BIAS AMP 2 puts the focus on dynamic tube amp behaviour and feel, adding new tube types and Amp Packs and enabling thousands of new custom amp designs in the process.

The new preamp tubes are all about headroom: The new 12BH7 and 12AY7 tubes put out more gain before distortion than normal 12AX7’s, so they’re often used in bass and hi-fi amplifier designs where being both loud AND clean is super important. You’ll find that these new tubes give you more control over clean and mid-gain guitar tones, making it even easier to create dynamic sounds that break up at just the right time - or not at all.

The new power amp tubes complement the low and mid-gain focus, offering more clean power and more saturation control. A pair of the 6550 tubes puts out the same power as four EL34’s, so they have more headroom at lower master volume levels. The new KT88’s have a similar midrange to EL34’s but the bass and treble frequencies extend lower and higher, making them ideal for slamming bass and hyper-clean guitar sounds.

BIAS AMP 2 also features two new amp packs, widening the palette of available tones and options. The Blues Pack was inspired by some of the best clean and mid-gain amps on the planet, offering increased touch-dynamics and a wide range of amp drive, while the Bass Pack was designed just for bass guitars, adding a host of studio quality bass sounds with zero tweaking needed.

The new tube types and amp packs offer a host of new dynamic possibilities, giving guitarists and bassists access to a huge new library of available tones and delivering sonic inspiration with every twist of a knob.

New Transformer With “Dynamic Tone Control”

The power supplies and transformers in tube amps do more than simply provide voltage to tubes and amplify signals - they affect the frequency response of the amp in fundamental and dynamic ways. We spent a large amount of time re-examining this behavior for BIAS AMP 2, and we came up with a new circuit we’ve added to the transformer module we call the Dynamic Tone Control. The DTC is a variable circuit that emulates the dynamic effect that power supplies and transformers have on the upper midrange response, and it can be really effective in adjusting the way the amp feels. The DTC can be magic on certain kinds of brash tones, so if you have a sound you love but it’s aggressive or brash in a way you can’t seem to control with EQ or circuit tweaking, try raising the DTC control. Higher values enhance the effect.

New Speaker IR’s From Celestion, And New Speaker Cabinet Module

For BIAS AMP 2 we partnered with Celestion, the king of speaker manufacturers, to give users access to the favourite impulse responses of top guitarists like Pete Thorn, Scott Henderson and George Lynch. Normal IR packs come with a mountain of files that are auditioned by loading them individually, but you can do all that work in BIAS AMP 2 simply by moving the virtual microphone on the speaker cabinet around. It makes using Celestion IR’s easier than on any other platform, and it’s not just a major time saver, it also allows you to stay in the creative mindset longer.

Studio engineers started recording guitar amps using multiple microphones as soon as they had the capability, and many Hall Of Fame guitar sounds were recorded using this technique. We’ve added this functionality to BIAS AMP 2, letting you use multiple microphones on the same cab and mix them together! Layering a dynamic 57 pointed at the dust cap (which picks up a ton of crispy treble and deep bass) with a 414 condenser aimed in between the dust cap and the speaker edge (which has less treble and more mids) results in a tone that is rounder and more full than either of those mics could produce by themselves. Now you can pull a solo out above the vocals or tuck a rhythm part behind the bass guitar just by tweaking the mic mixer.

The cabinet module also features brand new Open and Closed-back cabinet emulation, authentically recreating the distinctive bass and low mid frequency response that typifies each enclosure style. As a result, you have even more control over your core tone, allowing you to get even closer to iconic sounds with less effort.


Even though our ears are the most valuable tools we have when creating tones, sometimes it’s really helpful to be able to look at a tone visually. The new RTA EQ module displays a realtime frequency analysis of the signal running through it, making it easy to spot a problem frequency range or see what affect your circuit tweaks are having on the overall guitar sound. You won’t have to ask yourself “what is the frequency of that low midrange bump I’m hearing?”, because the RTA EQ will show it to you, allowing you to tame it quickly and easily.
