OVERVIEW

220W solid state bass head.

After months of research & development, Ashdown has designed a range of products that are equipped with more features, more power, new stylish designs and best of all, a dramatic reduction in size and weight. The Rootmaster range of bass amplifiers truly stands out from the crowd.

The RM-220 head features a comprehensive Pre Amp, with a classic 5 band EQ, an all-new compressor, plus footswitchable Drive and Sub Harmonic effects. A newly designed Class D power section helps to keep the weight down to below 12 lbs. Other features include a mini jack auxiliary input with level control, FX loop, XLR DI, Speakon/Jack combination out and a jack input for an (optional) FS-2 footswitch. The all new MAG RM range is the solution for bassists who need affordable and dependable light weight power houses that present real low-end power.

FEATURES
  • Flexible, lightweight, and high powered bass amplifier
  • Built-in compressor and footswitchable overdrive for added punch and growl
  • On-board Sub-Harmonic effect for added depth (footswitchable via optional FS-2 footswitch)
  • Comprehensive five-band rotary EQ; Shape function boosts high and low frequencies
  • Balanced XLR Direct Out; Effects Loop; Auxiliary Line In with Mix Control

Great tone, EQ and pro features. Order soon.

Comments about Ashdown Rootmaster 220W Bass Head:

The Ashdown rootmaster 220 is a good sounding, very HEAVY, smaller bass head. My purpose for this overweight little guy was to leave it at my practice area to avoid having to lug around my heavier Ashdown CTM100 Tube head. This being said, I was expecting more power, and less weight from this small class D portable head. I realize that 220 Watts is not that much however, when compared to a light weight 200 watt TC Electronics head or even a small Mark Bass, this Ashdown feels like it is 5x heavier, with less output. When paired with my TC 4x10, I have to push it (80-90% volume) to be heard over an acoustic drum kit even when the drums are played lightly.

This all being said, if it were just the prior mentioned cons, then I would not have felt as put off, as I got a great deal from MF. For me, the straw that broke the camels back was that my amp was missing one of the small rubber feet making the amp wobble, and sit at an angle on my cab. No big deal I figured I would reach out to Ashdown, and they would quickly resolve it by sending me a .25 cent replacement foot. To my surprise, I only got a response asking for my address, with zero outcome following. It has been 2 months, no further communication, no replacement foot. Poor customer service = no more customer purchases in my book. I will be selling this head, and replacing it with a quality made Aguilar Tone Hammer 300. Ashdown really needs to get their act together and turn up the customer service volume as this kind of lackluster service will unnecessarily cost them future revenue. If a company does not want to have quality USA support, then perhaps they shouldn't sell gear in the USA? There are too many other options to waist my time on this company. Shame.

Pros: Good tone, extra features such as overdrive and sub-octave built in. Attractive looking head.

Cons: Weak output, VERY LOUD fan, Octave tracks poorly, poor (UK ONLY) customer service, HEAVY (Not portable), only one speaker out.

Comments about Ashdown Rootmaster 220W Bass Head:

First unit was DOA. Second unit the Speakon hybrid output did not work with Speakon, but did work with 1/4" speaker cable. The built-in overdrive, suboctave and compression controls added some nice tone variations, but the FS2 foot pedal (optional) is proprietary and was out of stock and almost impossible to find.

        Comments about Ashdown Rootmaster 220W Bass Head:

        Bought this amp head on an SOTD. The sound, power and features are superb. Alas, though, the internal fan (which runs all the time) makes too much noise for me. I suspect that for the vast majority of players, especially those who perform (and even rehearse) at loud volumes, the internal fan noise would not be an issue. But I play at low volumes (house concerts and the like), and I like my gear to be dead silent when I'm not playing. A shame, since I really loved the sound from this amp.

        Comments about Ashdown Rootmaster 220W Bass Head:

        Mainly a guitar player, but I get the call for a bass gig now and then. I rebuilt my bass rig in 2011 but was never quite happy with it. I have always been a fan of the Ashdown bass sound and had another of their portable heads that really didn't thrill me. Both it and my previous amp were muddy. Could it have been my bass or my cab? By using each with different heads silenced those thoughts. So I started looking again for an amp in the 200w range and found this. Read the reviews watched the awful videos people made about themselves using this amp and realized the amp could be better than the demos I tprtired myself with. Figured "hey I've got 45 days...". It arrived today. 10 minutes later I put my other bass heads on the market. So long, fair well.

        I use this head with a no-name 2x10 housing a pair of re-coned high wattage speakers. My bass is a Curbow 4 with a Bartolini pickup and preamp. The last time my bass sounded this good I used a now out of production 150 lb back breaker.

        The EQ is perfect. At first my assessment was contrary only to find the EQ was punched out. The compressor is good. Better than a one knob control normally is. Wish it was foot switchable with the nice boost it adds. The drive is decent and not a feature I will make much use of. Being a parallel drive causes it to be as effective for the Cliff Burton player in you. The Sub brings a sweet thickness when kept counter clockwise of noon.

        I've heard there is a new, more powerful Neo edition on the way but I feel like it would be overkill unless I land a touring gig as a bass player.

          Comments about Ashdown Rootmaster 220W Bass Head:

          I took a chance and bought this amp for my Fender VI guitar (which is a cross between a bass and a standard guitar). Since it had an extensive EQ, I was hoping it was workable. I am totally blown away. Sounds amazing on the Fender, as well as on all of my guitars. The build on this thing is rock solid with a very thick metal enclosure, fan, direct out and more. I have owned many a nice guitar amp, nothing has come close to the build quality of this Rootmaster.
