The RM C210-500-T EVO II is the 500W bass combo with two 10” speakers designed for those looking for Ashdown tone, power and reliability without the weight normally associated with high-powered amplifiers.

Weighing just 18kg and delivering 500 watts of power through two 10” Whiteline Ashdown speakers, this amplifier is packed with quality and features. The Rootmaster EVO II range also features a built-in headphone preamp for silent practice, making these amps both gig-ready and practical practice devices.

The preamp features input jacks for use with both active and passive basses, creating a clear signal path to the input control which can be fine-tuned using Ashdown ’s signature VU meter. Once the signal has reached the optimum level, you can access the extensive features designed to sculpt and enhance your tone, such as the Shape (mid-scoop) button, full 5-band EQ and built-in compressor. The drive control, as always, offers delicious tube-emulated overdrive, while the octaver adds extra body to your tone; both can be foot-activated via the FS 2 footswitch (sold separately).

The rear panel is also feature-packed, featuring a balanced DI output, line input, FX Loop, headphone output, and a Neutrik Speakon/Jack socket for adding an 8 Ohm extension cabinet.

Finally, a handy Mute switch lets you tune and change instruments silently, with the VU meter switching from orange to a cool blue when mute is engaged.

Front panel in matt anodized alloy

Ashdown has updated the amplifier’s front panel with a matt anodised alloy finish, replacing the previous polished stainless steel. This simple but thoughtful change makes it easier to read the amplifier’s settings when under stage lights – no more reflective surfaces.

Simple and powerful EQ

The Rootmaster EVO Series preamp includes a passive and active input jack for use with high and low impedance instruments. The five-band rotary tone controls operate with surgical precision to give you total control over your sound, while the Shape switch allows for quick midrange work much like the famous ABM Series amplifiers.

One-knob compression

This easy-to-use, punchy-sounding compressor instantly adds warmth and body to your sound, offering power and evenness to ensure your bass fills any mix.

Overdrive and Sub-Harmonics

There’s a tube-emulated overdrive that can take the core sound of your bass and push it from warm overdrive to distortion whenever you need to add some punch and character to your tone.

For added depth and definition, an octaver is also present: the sub-harmonic generator allows you to select a sub-octave and activate it whenever you need extra depth.

Fully connected

If you want to use your favorite stompboxes or multi-effects, the rear panel features a Send and Return effects loop, a DI output for going live into your PA mixer or recording console, and a line input (with front-panel level control) so you can play along with a backing track during your studio sessions.

A pair of Neutrik Jack/Speakon sockets with a minimum 4 ohm load offers flexible pairing 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 features a built-in headphone preamp allowing you to practice in silence, making these amplifiers practical practice devices.
