Noise limiter an obvious example of why licensing good for electric music (except that in the hands of stupid local authorities I have known unaccompanied unamplified singers who could set them off).

Sybyn, it is possible to draft to free unamplified-level instruments rather than unamplified instruments from licensing, but if we can't even get the governing idiots to understand that amplifiers make things louder, what chance do we get of anything abit more subtle.
