Thank-you for giving the benefits of your two years of experience to us all. There are people here, who have been at it for a little longer. I am not even the most experienced here - and I began full time in 1979. At the end of the day what matters is not how loud you are but how good you are. Don Partridge and Phil Free (ever heard of them?) have never used amplification and they are still doing it in their seventies. Glyn Nicholas (ask any Aussie), Kieren Goss and Pete Morton, Mark and Simon, Busking Chris and Slippery Mike (to mention just a few) never used amps either and all were very successful buskers.
In certain situations it is virtually impossible to work without amplification. Among those situations is when the noise level is already very high, because other buskers are over amplified. The amplified South American bands of the eighties lost more towns to buskers than any busking opponents could have dreamed of. I would prefer to see quieter busking shows, but see them allowed in more places. Unfortunately, the trend seems to be going in the opposite direction.
