Overview

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.

    Comments about Ashdown Rootmaster 220W Bass Head:

    I finally decided to replace the 80s vintage bass head I'd been playing through for years. Ashdown has a good rep, and I got this one super-cheap as a Daily Deal. It took me about a half hour of tweaking, but I finally got the rich bass sound I was looking for. The five-band filter/EQ helped. There are a couple other tweaks that I'll experiment with over time, like Sub and Drive. The head is very small, but fortunately has a fan to help keep it cool. It's not what I would call heavy compared to my old bass head, but it's heavy for its size. Two biggest drawbacks about it is that is has no handle and that it has to be run about three times as high to achieve the same output as my old amp in spite of the fact that their outputs are listed as the same. But overall, it's done a great job so far.

      Comments about Ashdown Rootmaster 220W Bass Head:

      I have had my eyes out for a quality bass head for my home studio. After months of researching & trying out various heads It was down to a couple choices ~ so when the Ashdown MAG220 showed up as a GC "daily pick" for under $200, I couldn't order fast enough! It arrived on time & in excellent condition! WOW ~ what a great head ~ sporting a 5 band EQ, compressor & sub-harmonic generator. I can see that even rated at 220 watts, it might be a bit anemic for playing in live venues, but as for me & my needs, it is proving itself as indispensable. Can't go wrong with this one ~ Quality & Value all the way!!!
