Introducing the Ashdown RM-500 EVO II, the ultimate amplifier for those who demand Ashdown's signature tone, uncompromising power, and unwavering reliability without the cumbersome weight. Weighing a mere 2.1KG (4.6lbs), this compact dynamo boasts an impressive 500 watts of power and class-leading quality and features.

One of the standout features is the onboard headphone preamp, transforming this amp into a versatile practice device for silent rehearsals. It accommodates both passive and active instruments, ensuring a pristine signal path to the input control, complete with Ashdown's trademark VU meter for precise level adjustment.

But that's not all – the RM-500 EVO II offers a wealth of tonal sculpting options. The 5-band EQ, onboard compressor, and tube-emulated overdrive give you complete control over your sound, while the sub-harmonic controls add extra depth. These features can be foot-switched using the FS-2 foot-switch (sold separately), offering exceptional flexibility.

The addition of a mute button, illuminated in cool blue, adds a touch of stage presence, and the matte alloy front panel eliminates reflections under bright lights. Whether you're performing on stage or perfecting your craft in the studio, the Ashdown RM-500 EVO II delivers unparalleled tone, power, and style.

For added versatility, the amp offers send and return sockets, a DI output for seamless integration with PA systems, and a Line Input for rehearsing with backing tracks. Partner it with Ashdown's Rootmaster EVO cabinets for a perfect match. With the RM-500 EVO II, your sound will be smooth, powerful, and ready for any stage or studio setting.


Matt anodised alloy front panel

Ashdown have upgraded the amp’s front panel with a matt anodised alloy finish, replacing the previous polished stainless steel. This simple, yet observant modification makes reading your amp settings that bit easier when placed under bright stage lighting.

No more reflective surfaces.


Simple, powerful EQ

The Rootmaster EVO series’ pre amp now includes a passive and active input jack socket for use with high and low output instruments. The 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.


One-knob Compression

Instantly adding warmth and body to your tone, this simple to use, great sounding compressor delivers a powerful, even sound to make sure your bass is smooth as silk and will fill out any mix.


Overdrive & Sub

With footswitchable flexibility, our tube-emulated overdrive can take your core bass sound and push it into warm overdrive through to distorted filth whenever you need to add extra grind and girth to your tone.

Bringing extra depth and definition to your bass parts, the Sub-Harmonic Generator lets you dial in a sub-octave and kick it in via footswitch whenever you need the extra depth for those super-heavy Godzilla moments.


Totally connected

If you want to use your favourite pedals or multi-effects, you’ll find send and return sockets on the back panel, along with a DI output for direct injection into the PA mixer or recording console and a Line Input (with front panel level control) so you can jam along with a backing track in rehearsal.

A pair of Neutrik Jack/Speakon sockets with a minimum 4 ohm load provides flexible partnering options with a dedicated range of Rootmaster EVO cabinets. The Rootmaster 500 EVO II can be used to power a single 8 ohm cabinet, a pair of 8 ohm cabinets or a single 4 ohm cabinet.


Headphone Output

The Rootmaster EVO II range now comes equipped with an on-board headphone preamp to allow for silent practice,which doubles up these gig-ready amplifiers as handy practice devices. The headphone preamp maximises the full sound potential of your headphones, so now your in ear sound can match the quality of your stage sound… given you have the correct (Meters Music) headphones, of course!
