Ashdown RM 500-EVO II Lightweight 500w Head

Ashdown's fantastic Rootmaster bass heads have now reached their second evolution with the RM-500 Evo II! This 500 watt powerhouse is now even more lightweight than ever - almost half the weight of the original RM 500! - and has been specially developed to maintain a deep low end, well-defined mids and transient highs, delivering its output into a 4 Ohm load.

The Perfect Choice for Working Bassists

New additions to the Rootmaster EVO series pre-amp include a passive and active input socket - for use with low and high output instruments respectively - an upgraded power section, and a handy mute button. The clear signal path from your instrument to the input control enables you to finetune your input level with that famous Ashdown VU meter, and once the signal is at its optimal level you are awash in those rich features designed to enhance your tone.

Bags of On-Board Features

With it's Shape button, 5-band EQ and on-board compressor, Drive control, and sub-harmonic controls, your tone-shaping options are many and varied. Whether you want to push out the purest, bright, clean tones, or delve into the realms of valve-emulated overdrive with fat sub-harmonics to really beef up you sound, the RM-500-EVO II has got you covered.

Easy to Gig With

A new, lightweight model, the RM-500-EVO II is most certainly the perfect choice for working bassists that need all the power of a 500 Watt solid-state head, but without the excess weight - in fact it weighs just 5 KG (just 11lbs), which is significantly less than most other amp heads in the same category.
