Product Description

Positive Grid annouces a free update that adds reverb functionality to their BIAS line of professional amplifiers. The update for BIAS Amp, BIAS Head and BIAS Rack includes nine different reverb types, covering a wide range of reverb colors and sounds. More than just a simple two-knob design, the user has control over not just Reverb Type, Decay Time and Mix, but also Damping (which simulates the sonic affect of absorptive material, softening the high-frequency response), both a Lo and Hi Cut filter, and Dwell (which operates as a saturation control).

Insane Tone Possibilities! The world’s first cross-platform guitar amplifier, BIAS Head integrates seamlessly with BIAS Amp for mobile and desktop use: you can design your custom amp and create Amp Match models in real time.

Next Level Amp Tone
BIAS Head is a guitar and bass amplifier that accurately captures any amp tone in the world, including the cab and even mic position. You can safely connect your cab into its powerful Class D 600 Watts RMS at 8 Ohm or 300 Watts at 16 Ohm. With the included BIAS Amp Pro software, you can share and download thousands of amp match models and save them right in the head.

New Kind of Amp
Hardware and software beautifully integrated, BIAS Head allows you to design and match any amp tone on the fly, share and download Amp Match models in the cloud, and use that massive tone on a full-blown 600w RMS power amp.

Amp Match and ToneCloud
BIAS Head comes with Amp Match® technology, which lets you precisely match the nuanced tone of any classic, modern or boutique amp and load custom cab and mic responses. You can share or download thousands of Amp Match models from ToneCloud.

Premium Components
The op-amps, passive components and A/D and D/A converters used are all top of the line. BIAS Head’s power amp is optimized to perform any BIAS Amp presets at the highest audio quality possible at any volume. It also provides zero latency performance due to its built-in interface.

Amp Match
Amp Match® lets you capture or download any tube amp tone and sync it with your desktop and mobile devices. You can then use the exact same tone with BIAS Head on stage, in the studio or while practicing at home.

Amp Design
Design your custom dream amp and sync unique presets in real time. Swap out the virtual tube types, preamp, transformer, tone stacks, cab and mic position to create your own signature sound, with just a few taps or mouse clicks.

Thousands of Amps
Download thousands of Amp Match® models created by legendary recording artists and your fellow guitarists on ToneCloud, and sync the entire collection across your desktop and mobile devices and BIAS Head in a snap.

Amazing tone out of my amp

What is your opinion of this product?
To be honest I haven’t messed with the configurations much because I just hooked this amp to my Orange cab and mi guitar and the out of the box settings give me everything I’m looking for. The tone is incredible and this works like an amp. Simple, to the point and amazing tone out of the box.
