ASHDOWN UK-RBM-500 RBM - ROOTMASTER 500 Head made in the UK
The UK-RBM-500 amp head (Rootmaster Bass Magnifier) continues the Rootmaster philosophy: powerful sound in a compact, portable format, ideal for the stage. Made in the UK, it features a stunning Glacier Blue finish.
Its intuitive tone-shaping tools include Ashdown’s Sub-Harmonic Generator—a classic for added depth—a musical built-in compressor for balanced dynamics, and a tube-emulated overdrive circuit capable of adding subtle texture or hard-hitting saturation. An effects loop allows easy integration of pedals, while DI and DI with analogue cab simulation outputs provide straightforward solutions for live or studio work, with consistent, mix-ready results.
With a dedicated headphone output for silent practice and rugged British build quality engineered for long-term reliability, the UK-RBM-500 stands out as a versatile, compact option delivering exceptional sound for professional bassists who need a high-performance amp for the rehearsal room, stage, or home.
