I know that this has probably been covered on more than one occasion but I am having difficulty finding a concise thread on the topic. I find myself on the verge of a new project that will require me to have an actual amp/speaker combo. For the past 15 years in my electric duo I have been simply running a Tech 21 bass DI direct and sending my needs back through the monitor mix. My last go-round with amps and cabs was a SWR SM400 and Goliath 4x10 cab which I just loved. But I am older and a bit more broken down now and am totally digging teh smaller, lighter heads and cabs. I am excited by the prospect but find myself overwhelmed by the variety of small product available. So, that said, I'd love your opinions and recommendations on a compact bass amp head. I have been looking into the Eden WT550, TC Classic 450/RH450 and Markbass F1 if that helps you know where my head is at. They all look very good but I am unsure of the real world (if any) differences between them. Cab choices I have been mulling are (respective to whatever head I choose) are the Eden 210XLT/XST or just looking into the TC RS201's. The TC stuff really looks like it would suit me well but I would like to hear some opinions on some other gear that perhaps I have not yet even considered. I'll be primarily using a Modulus Q5W w/ EMG's and I like a 'modern' sound. Music will be mostly classic and modern rock covers. Do newer, stacked 2x10 cabs actually match or surpass the quality of a single 4x10 cab of the same type? Is there a loss of the lowest end with two smaller cabs vs. one larger or has that been overcome? Thanks.
