Manufacturer's Description
Ashdown Engineering RM-MAG-420 Rootmaster 420W Bass Amp Head
At Ashdown, we know that not every gig pays the big bucks. Dedicated to busy, hard-working bass players on a budget, Rootmaster heads, combos and cabinets draw on all of our experience working with some of the biggest bands in the world to deliver workhorse reliability, creative tone-shaping, comprehensive recording and performing facilities plus the sonic slam you need to underpin your band’s performances night after night – all at a price that won’t break the bank.
Powered by a new 420 watt digital power section, the RM 420 is the lightest RM head, weighing in at just under 4kg and the perfect choice for working bassists looking for power, tone and features without the weight.
Simple, powerful EQ
It all starts with an ultra-low-noise instrument input where the accompanying Input Level control helps you perfectly match the output of your bass. 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 cabinets. 2 x 10”, 1 x 15" 4 x 10” and 6 x 10"” cabs all feature custom-designed Ashdown bass drivers plus a high-frequency horn for additional top-end bite. All cabinets feature ultra-cool retro cloth grilles, road-ready tolex covering and tough metal protective corners.
