Overview

Huge power, tone and versatility from a portable head.

The RM-800 head features a comprehensive preamp, with a classic 5-band EQ, compressor, plus footswitchable Drive and Sub Harmonic effects. A Class-D power section helps to keep the weight down. Other features include a mini jack auxiliary input with level control, FX loop, XLR DI, Speakon/Jack combination out and a jack input for an (optional) FS-2 footswitch. The RM-800 range is the solution for bassists who need an affordable and dependable lightweight powerhouse amp that provides real low-end power.

The EQ
The 5-band rotary tone controls act with surgical precision to provide total control over your sound, while a shape switch instantly dials you into a classic Ashdown tone setting, straight from the world-famous ABM.

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.

Overdrive & Sub
With footswitchable flexibility, Ashdown's 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 favorite 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 combined Jack/Speakon socket with a minimum 4 ohm load provides flexible partnering options with a dedicated range of Rootmaster EVO cabinets (sold separately).
