Positive Grid Announces the BIAS Rack Amp

Positive Grid has expanded their BIAS Amp lineup with a new rackmount version. The BIAS Rack integrates hardware and software to allow bass and guitar players to capture “any amp tone in the world.”

Positive Grid BIAS Rack Amp

The unit ships with BIAS Amp Pro software for Mac and PC, which allows users to capture and load simulations of the tones of popular bass amps via USB all the way down to the cab and mic position. “Amp Match technology analyzes and compares a selected BIAS amp model with the sound of a target amplifier, cab, and mic,” Positive Grid writes. “It then executes the tonal compensation and enhancements needed to make an amp model’s sound accurately match the target amplifier. BIAS Rack’s 600w gives users more headroom and cut in a live situation–all at zero latency.”

For players that love tweaking, you can even design your own virtual amp and sync unique presets in real time. The virtual amp builder lets you swap out tube types, preamp, transformer, tone stacks, cab and mic position to dial in your own unique sound.

Its power section runs 600 watts at 8 ohms or 300 watts at 16 ohm. Other features include an Effects loop, a headphone output, an XLR direct output, MIDI In/Out/Thru, and Bluetooth connectivity. The Positive Grid BIAS Rack is available for pre-order for $1,049. It will start shipping later this year with a regular price of $1,299.
