The PureAmp high-fidelity Hass Power Amplifier by GRBass

Option as: 350 Watts or 800 Watts

The GRBass PureAmp is a compact, high-fidelity bass power amplifier designed for players who want to use their own preamps, pedals, or instrument electronics while keeping the original tone completely transparent.

Available in PureAmp 350 and PureAmp 800 versions, it offers a lightweight solution with professional power output and a built-in DI output for live and studio use. Its compact size, low weight, and clean amplification make it ideal for bassists who want maximum control over their own tone shaping.
