I played a Roland Cube 80X the other day and was really blown away by the clean blackface and tweed tones, especially with all of the low-end thump. I'm thinking about getting the 80X, but I know that the new 80XL is out now. It seems like Boss occasionally updates their COSM technology; they apparently updated the amp models between the cube 60 and 80 and (unlike some), I really prefer the 80. Does anyone know whether the 80XL reflects a similar jump in modeling quality over the 80X? If there is a tradeoff, I'd rather take the better amp models over other "features." The only other additions of the 80XL are: 1) an "extreme" model that I will never use; 2) a "heavy octave" effect that I will never use; 3) 80-second looper instead of 40 - I probably wouldn't notice; 4) NOTE - the new 80XL's delay section only has "delay" and "looper," while the old 80X has both "warm" (analog) and "clear" (digital) delay, as well as a looper. Anybody compare the two?
