Some questions to those of you who busk on the street.
If you are using an amp for your instrument and mic, how do you get the power source?
If you are using those battery operated amp, what brand are you using and how much is it?
most i have seen are battery powered amps, they cost from 400- 600 SGD. a full charge can last the whole day. there are a few made by roland. I think I saw a few on swee lee.
