All the resistance to over 30 lb. arrangers, and here we are talking about 50 lb+ amps...
Maybe the next time you sneer at a guitarist using two speakers on poles and a self powered amp, you MIGHT consider that each of those components doesn't weigh more that 25 lb., probably. If sticking them up on poles, widely separated is what annoys you, you can always put them on the ground in exactly the same place you would have put a keyboard amp.
Dee...taa......Deeeee!
And also remember, there's a reason they are elevated speakers... The minute the crowd gets up and dances in front of you, there goes the sound for the rest of the room... You sound like mud, and no-one can hear the vocals.
Weren't you the one who chose NOT to go with a G70 because it was 45 lb., despite having all the foot controls and other things you hated weren't on the E60?
