Independent shopping perspective
The Korena take
Rootmaster RM-800 EVO II puts 800W of bass amplification in a 5.5 lb head built for players who need substantial headroom without a heavy rig. Separate passive and active inputs feed an input control monitored on Ashdown’s VU meter, followed by a shape switch, 5-band EQ, compressor, drive, and sub-harmonic controls. A headphone preamp gives it a quiet-practice role as well. For stage changes, mute switches the meter from orange to blue.
Strong match
Who this is for
- Larger-stage bass rigs where 800W output and high headroom are the priority.
- Silent practice through the onboard headphone preamp.
- Bassists switching between passive and active instruments using dedicated input jacks.
Consider the trade-offs
When to look elsewhere
- Players who require footswitch operation of drive and sub-harmonic controls without purchasing an FS 2 footswitch.
