Ashdown Rootmaster Bass Magnifier 500w

The UK-RBM-500 (Rootmaster Bass Magnifier) amp head perpetuates the Rootmaster philosophy: powerful sound in a compact, portable format, ideal for the stage. Made in the UK, it boasts a superb ice-blue finish. Delivering 500 reactive watts, this lightweight amp head is designed for demanding bassists who want the versatility of professional gear without the bulk.

Its intuitive sound-shaping tools include the classic Ashdown subharmonic generator for added depth, a musical integrated compressor for balanced dynamics, and a tube-simulated overdrive circuit capable of adding subtle texture or punchy saturation. An effects loop allows easy integration of effects pedals, while DI and DI outputs with analog speaker cabinet simulation offer simple solutions for live or studio work, with consistent, mix-ready results.

With a dedicated headphone output for silent rehearsals, and robust British build quality designed for long-term reliability, the UK-RBM-500 presents itself as a versatile, compact and great-sounding option for professional bassists who need an amp that performs as well in the rehearsal room as it does on stage or at home.
