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.

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.

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.

The Rootmaster EVO II range now comes equipped with an on-board headphone preamp to allow for silent practice,which doubles up these gig-ready amplifiers as handy practice devices. The headphone preamp maximises the full sound potential of your headphones, so now your in ear sound can match the quality of your stage sound… given you have the correct (Meters Music) headphones, of course!
