Product Description


Ashdown RM-500-EVO 500w Lightweight Bass Amp Head

Premium Ashdown Quality

The Ashdown Rootmaster 500 Bass Amp Head is the lightest RM head, weighing in at 4.5kg making it the perfect choice for working bassists who are looking for all the power and features but don't want to carry around heavy equipment. Rootmaster heads, combos and cabinets draw on Ashdown's experience working with some of the biggest bands in the world to deliver workhouse reliability, creative tone-shaping, comprehensive recording and performing facilities plus the sonic slam you need to underpin your band's performances night after night.

Simple & Powerful Controls

Perfectly match the output of your bass with the active and passive inputs and accompanying Input Level control. Five-band rotary tone controls act with surgical precision to provide total control over your sound, while a Shape switch instantly dials you in to a classic Ashdown tone setting, straight from the world-famous ABM. Your bass will fill out any mix by instantly adding warmth and body to your tone thanks to the great sounding compressor that delivers a powerful, even sound.

Drive and Sub Generator

Adding to the player's sonic arsenal, the RM-500 also comes loaded with Ashdown's Tube-emulated Overdrive, adding character that ranges from warm overdrive through to distorted filth. There's also a Sub-Harmonic Generator that blends in a low-octave, great for adding depth and definition to any part. Both Drive and Sub are switchable from the front panel or via an Ashdown FS2 footswitch.

Totally Connected

The Ashdown Rootmaster 500 offers many different connectivity options. Jam along with a backing track in rehearsal with the Line Input with front panel level control, as well as using your favourite pedals or multi-effects with the return sockets on the back panel, along with a DI output for direct injection into the PA mixer.
