I’ve gigged with a bunch of Yamaha arrangers. My observation is that in most social situations, parties, etc., the average person will not notice, or pay attention to sound gradations between arrangers-----unless, for some reason, they are curious about arrangers, have some musical experience or interest, know and like the performer, want to chat afterwards, and other such matters. The more relevant factor is the entertainment issue, as Gary pointed out. Whether one gets applause or glowing reviews often revolves around the circumstances at the time----song selection, presentation style, audience participation, environmental concerns surrounding the gig, maybe the weather, how folks are feeling during the gig, and who knows what? Not necessarily the sound of the instrument. You win sometimes and feel like you’re on a roll. Other times, you wonder what may have gone wrong. Sometimes, even a first seeded team is beaten by a 16th seed. And, the first seed might have been playing a Genos.
