With you all the way. Over the years I've had Trace Elliott, Barefaced, TC, Peavey, Ashdown... Then last summer I bought into a Markbass LM3 head and 410 STD cab. Great balanced bass sound for me, surprisingly portable, no issues indoors or out. It just - WORKS. My definition of professional.
FTR, on the sound front for me EQ at 12 o'clock settings on the LM3 is fine in band context, but not when practising or on my own, when settings of 12, 11, 10, 9 and with the filters at 8 and 10 are perfect.
