Positive Grid BIAS AMP 2 is an amp simulator plug-in with extensive customization options. Swapping the preamp and power amp sections as complete blocks can dramatically change its tonal character. You can further fine-tune the sound by choosing tube types and speaker cabinets, and by using microphone models based on familiar microphones such as the SM57 and MD421. Combining these features lets guitarists shape detailed amp tones in a DAW, helping improve the sound of recordings and live streams.

Make Dramatic Tonal Changes by Swapping Entire Sections

Even if you know you can change the amp’s internal components, you may be unsure where to start.
In that case, we recommend replacing an entire preamp or power amp section, since these sections form the core of the sound.

PREAMP

The PREAMP section offers a variety of configurations suited to different genres and types of sound.
Try them while playing, and look for a sound close to what you have in mind.

POWER AMP

You can change the POWER AMP section in the same way.

Combining these two sections can dramatically transform the amp’s tonal character.

Tube Types

For more detailed customization, try changing the tubes in the preamp section.

As shown here, the selected tube type changes the sound.

Using the Cabinet and Microphone Section

The speaker cabinet is an essential part of shaping your sound.

BIAS AMP 2 includes a variety of cabinet types.

Frequently Asked Questions

Q1. I’m new to customizing amps in BIAS AMP 2. Where should I start?

Start by auditioning configurations in the PREAMP section and choosing one that suits your genre or desired sound. Then combine it with a POWER AMP section to establish your basic tone. From there, refining the cabinet and microphone settings is an efficient way to fine-tune the sound.

Q2. How much does changing the tube type affect the sound?

Different tube types produce distinct tonal characters. Changing the preamp tubes alters the gain characteristics and harmonics, letting you achieve different tones with otherwise identical amp settings.

Q3. How should I divide the roles when using two microphones?

One suggested approach is to use MIC 1 for the high frequencies and MIC 2 for the low and mid frequencies. You can also reverse their roles, so adjust the balance to suit your preferences.

Q4. What speaker cabinets are included in BIAS AMP 2?

The article does not list the individual cabinet models, but several cabinet types are available. You can fine-tune the cabinet and microphone setup, including open-back/closed-back options and microphone positions. Choosing a cabinet lets you further refine a sound created with presets.
