The highend is open and clear, it's not harsh at all though. I found the 2 mills cabs I had to both be a little overly bright and even a little harsh. Not the case with the Grand Canyon. The bass is VERY tight, Ive had the Fatbottom cab more than once and its in that realm but just doesnt sound like a front loaded cab if that makes sense. To be honest for a while I thought the Grand Canyon was the best sounding cab Ive had because of the openness and clarity. It's more recently that I found myself wanting more lowend. I think I might like it even more with different speakers possible but right now mine has V30s which I love in general but maybe more bass heavy speakers would be a better match, Im not sure.
