Description
Delivering 500 watts of responsive power, this lightweight amp head is designed for discerning bassists who want the versatility of professional gear without the bulk.

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.
