Overview

Now in its second evolution is the RM-500. The 500-watt power section of the RM-500 EVO has been developed to maintain a deep low end, defined mids and transient highs delivering its output into a 4-ohm load. Ashdown Rootmaster heads are the perfect choice for working bassists looking for power and features without the weight.

The Rootmaster EVO series’ pre amp now includes a passive and active input jack socket for use with high and low output instruments, this sets a clear signal path to the input control enabling you to fine tune your input level using the trademark Ashdown VU meter. With the signal at its optimal level, you then hit the rich features designed enhance your tone, such as the shape button, 5-band EQ and on-board compressor. The drive control, as always delivers a delectable valve emulated over-drive, whilst the sub harmonic controls add further fatness to your tone - both can be foot-switched via an FS 2 footswitch (sold separately).

Rootmaster EVO heads also feature an upgraded power section plus a handy mute button. What’s even cooler is when switched to mute, the trademark Ashdown Engineering VU meter changes from orange to cool blue – creating the perfect on stage mood lighting between sets.

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 will fill out any mix.

Footswitchable variable overdrive
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.

Kick it down
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.

Create the perfect rig
A combined Jack/Speakon socket with a minimum 4 ohm load provides flexible partnering options with a dedicated range of Rootmaster EVO cabinets. Ashdown’s 1 x 12 in., 1 x 15 in., 2 x 10 in. and 6 x 10 in. cabs all feature Ashdown White Line speakers for a refined tone, plus a high- frequency 3-way controllable tweeter for additional top-end bite.

    Comments about Ashdown Rootmaster RM-500-EVO 500W Bass Amplifier Head:

    This amp has proven excellent since it arrived last month. I was worried when I started looking for a new amp as the only thing anyone mentioned was how their amp sound with electric. This amp sounds great both in the studio and at gigs on electric, but I'm happy to say my upright sounds great through it, too. I get a much warmer sound on upright than my old Acoustic Image Coda provided, as the 5-eq lets me easily adjust to whatever environment I'm in. The built-in compression gets some use, but I stick to my pedals rather than use the built-in drive or octave. Have experienced no issues with overheating and it's built sturdy and portable. Would recommend this to anyone looking for an amp that works well with electric and upright work.
