Lots of problems that aren't really problems seem to be coming up. Honestly, taking everything into account here no one'd ever go out live again.
As technology gets better, cheaper & smaller, I reckon we will see significant falls in sales of big old fridges & the like, however highly regarded they are.
There used to be an outfit around these parts where the bassist would take an 8x10 & monster valve head out to every single gig, be it the Dog & Duck or 300 capacity theatres. The gear looked great aye, but the word amongst the bass playing fraternity was that it was a bit cockish tbh. Used to love holding my hand out for a high five as we'd pass on various venues' staircases, me with a modest combo & this guy's eyeballs bulging out as he did the Pickfords shuffle out to the van XD
