I A/B a Mesa Boogie 115 to a SWR 115 and found the Mesa to be a much more deeper tone with the highs not as sharp but there. The SWR SOB, with tweeter shut off for equal comparison, was not as bottom heavy and the highs were more predominant and clear. I say this without suggesting either tone is necessarily better and setting off a product war thread. I've read people saying the SWR's are colored. Maybe the sound I hear from the SWR is actually colored to be that way but it seemed to me a more uncolored tone as compared to the Mesa. You think John Paul Jones would prefer a bass cab (he plays SWR) that is known for coloration to one degree ? I would think he of all people would like his basses to make the tonality not a manufacturers engineering department BUT who knows money talks !!
