Well, I just had a gig enquiry come in, to play at a garden party. Acoustically. So we contact the rest of the band, and say "Gig offer. Not a lot of money, but it wont be hard work, it's acoustic". We all speak the same language, English, and speak it fairly fluently. We all know what the enquiry means. Acoustically=no PA to carry in,set up, and fiddle with to get the sound right. Simple. And bleeding obvious, till recently, when the new meaning of "acoustic" as "only a bit amplified" started creeping in. I am just registering a protest that is a new meaning that is merely confusing to me. Not to say irritating.
