AshdownRootmaster RM-500 EVO II 500W Bass Amp Head
1/4
Independent shopping perspective
The Korena take
At 5.73 lb with 500W output, the Rootmaster RM-500 EVO II is a bass head for a compact, full-featured rig. Passive and active inputs feed a preamp with a five-band EQ, Shape control, compressor, Drive control, and Sub-Harmonic Generator. A headphone preamp supports silent practice, while the line input can bring in backing tracks for rehearsal. On the rear panel, effects-loop connections, a balanced DI output, and two Speakon outputs cover pedal integration, direct feeds, and speaker connection.
Strong match
Who this is for
- Silent bass practice through the onboard headphone preamp.
- Rehearsal sessions using the line input for a backing track.
- Stage or recording feeds using the balanced DI output.
Consider the trade-offs
When to look elsewhere
- Players who require FS 2 footswitch control without purchasing the separately sold footswitch.
