Critic Reviews

Positive Grid Bias Mini Guitar & Bias Amp 2 Pro

soundonsound.com

The Positive Grid BIAS Mini Guitar Amplifier showcases impressive build quality and sound performance, delivering convincing tube amp emulations and a versatile software experience with BIAS Amp 2 Pro. The intuitive preset management makes it easy to create unique sounds, and it integrates well with pedals. However, it falls short with limited onboard effects—most notably the absence of a spring reverb—and lacks phantom power protection, posing potential risks when connecting to certain audio systems. While it excels in many areas, these shortcomings may deter some users seeking comprehensive functionality. Overall, it's a powerful tool for both live performances and studio work, particularly for those who value customizability.

The Positive Grid BIAS Mini Guitar Amplifier packs a surprising punch in a compact package, effectively serving as a versatile solution for gigging musicians. With a built-in 300-watt power amp, it delivers ample volume and features an intuitive control panel for easy adjustments on stage. The integration with Bias Amp 2 software opens the door to extensive tonal customization, making it a powerful tool for tone-chasers. However, the small size may compromise some heft and presence that larger amps provide, potentially leaving purists wanting more. Ultimately, it’s a strong contender for those looking to streamline their setup without sacrificing sound quality.
