I've finally gotten so old I mostly no longer listen with my eyes.For me it is 100% about aesthetics, especially the cabs. The name combined with that color scheme and carpeting just looks so bad. So I never considered MarkBass. Even Michael League asked for something more pleasing to the eyes when they made his signature amp. I do wish they sold more stuff that looks like his rig.
I get that a lot of famous players use their stuff, but they probably get it for free. If it's free and sounds good I'd play a turd shaped amp.
