I have to agree on the fender solid state and the Ampeg solid state combos somewhat as well also. To me they sound like they are choked off in the low end department somewhat. I true like the rumble combos brightness though. The 200 and 500 combo soynded pretty good in guitar center with a P Bass but I was noticing they didn't quite want to produce the full low end. It was slightly choked off it seemed but not bad. The rumbles did soynd pretty damn good for their price I thoyght, but I have the 40 watt and u might as well not bother. It's good for hearing your bass to tune it at home but that's about it. Pretty thin sounding
