Reviewed: Positive Grid BIAS Distortion Twin - Mixdown Magazine

The Positive Grid BIAS Distortion Twin is a powerful and versatile pedal that offers a wealth of tonal options with its ten built-in presets and extensive customization via Bluetooth-enabled software. Its user-friendly design makes it easy to dial in your sound, and the robust construction ensures durability on stage. However, while it excels in versatility and ease of use, some players might find the learning curve of the software a bit steep at first. In the end, this pedal is ideal for those seeking a comprehensive distortion solution, but it might overwhelm simpler setups.
