I bought an RS 210 last summer and its been my main amp since. We are a 4pc Modern Rock cover band and it worked perfectly. It has enough power for the guys to hear me and then some. If I can, I'll put it on a chair, but usually its on the floor pointed toward me a bit. The controls make very big changes in the sound. For example, the bass control is pretty touchy, the change from 12 O'clock to 1 O'clock is very noticable. That can be a good thing for bad thing depending on if you are happy with your sound that day

I don't use the seperate para eq, and run the line out to the board.
I don't rely on the amp to fill the room. The PA provides the bulk of our sound as we mike the guitar, kick and my line out (vocals of course) We run a medium sized bi-amp setup. EAW 12+tweeter (I think with a 1200w Crown, but we don't have it full up. Maybe pushing 800w) with a single 1x15 powered sub (Not sure the power on the sub. Not a ton). Never any complaints about the bass not being loud enough (but of course I have had to turn down, lol). A few times I've let guys sit in and its sounded pretty good to me out in the audience !! Only problem is that some places we play have raised floors and that can get a bit boomy for any bass amp.
This replaces an SWR BASS 350 and Goliath III. For outdoor gigs, I've used the Nemesis with the SWR cabinet as an extension. The SWR is more 'hi-fi' sounding. When I A-B them at home, the SWR seems overly bright. The Eden is more low-midrangy. But they are both very good amps and the power and tone shaping is functionally similar I would say. And both are 300W amps.
Negatives - The blue glowing flourecent logo looks really cool until you need to make an adjustment at a gig. You can't see the position of the black knobs on the black faceplate with 50 million candlepower of Blue glowing away

I took some liquid paper and put a white dot where the knob marker is, and that helped.
The parametric eq is kinda useless (for me anyway). It doesn't really add or filter anything usefull for me in particular. I keep it bypassed for the most part.
Lots of options, lot of punch and power, easy portable package, moderate price. Beats draggin around a 2x10 and head all weekend, thats for sure !!
