    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 to 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, 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.
    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.
