Presentation
The Ashdown RB-800 amp is the ultimate tool for bassists seeking power and sonic flexibility. Designed and manufactured in the UK, it benefits from Ashdown's expertise and the signature sound of Pantera bassist Rex Brown. Offering 800 watts of power, it adapts to any environment, from live performances to studio sessions.
With its 800W of power, the Ashdown RB-800 is a bass amplifier designed to stand out in any setting. This model stands out for its modeling amplification design, which allows its sound to be adapted to a multitude of styles. Thanks to the Ashdown subharmonic generator and compression control, you achieve perfect definition, even in the lowest frequencies.
This model boasts an impressively wide frequency response ranging from 22 Hz to 25 kHz, providing full coverage of the sonic spectrum. The 5-band EQ system allows for precise adjustments, with bass, midrange, and treble controls to sculpt the sound to your liking.
The RB-800 also lets you choose between two speaker types (10" or 15") and enable or disable a high-frequency boost for more impactful sounds. The ability to choose between a bass reflex or closed-back cabinet opens up additional options for fine-tuning the low-end.
This amplifier boasts many innovations, particularly its analog cabinet simulation, which allows you to realistically simulate a speaker output using the XLR D.I. switch. This feature is ideal for direct recording or live performances with PA systems, providing great clarity without the need for a real speaker.
