Critic Reviews

Positive Grid BIAS Distortion Pro review | MusicRadar

musicradar.com

The Positive Grid BIAS Distortion Pro pedal is a promising venture into hardware from a software-centric company, offering customizable distortion effects and solid build quality. However, it falls short due to a noticeable lag in its boost switching, which undermines its live performance capabilities. While it provides impressive tonal flexibility through its software integration, the inability to stack distortion effects diminishes its versatility. For those seeking a robust workhorse, the pedal's presets may suffice, but the competition offers stronger options, leaving the BIAS Distortion Pro in a challenging position in the pedal market.

The Positive Grid Bias Distortion Pro pedal delivers a versatile array of classic tones in a robust and user-friendly package, ideal for both live performances and studio work. Its extensive MIDI capabilities and customizable presets make it a powerful tool for tone shaping. However, while the pedal excels at producing a wide range of sounds, some users may find the depth of options overwhelming. Overall, it's a solid choice for guitarists looking for flexibility, but those seeking simplicity might feel lost in its vast features.
