I never would have guessed that the issue of buskers using amplification in Dublin could be as close as just one vote: https://counciltracker.ie/amendments/ebfbb7f0 … Personally I'd prefer to see a wattage or decibel limit, to allow music forms that need a speaker, but without the blast.
The city could sell a small-wattage amp, probably around ~150EUR, as part of the licensing scheme. Pretty easy to make it identifiable. Hell, maybe this should be a side-business for me ;-)
