Buskers and electric shocks

Well now I know what the word busker means. Damn US schools, oh wait, I nev er paid attention..... I was too busy learning shit....... (go ahead)

Anyway, the cheapest and easiest way I can think of is to just take the gro und of the instruments' inputs and wire them to a wet rag laying on the gro und, just fold it up and put the wire in between. Just pour water or beer o n it from time to time, like when you are again getting zapped. Don't worry about grounds on the rest of the shit.

BTW, isn't there some sort of 12 volt syatem that can eliminate all this ex tra bullshit ?

In Car Entertainment stuff is not structured for use by buskers. Otherwise off-the-shelf 12V "leisure" battery+inverter+SMPS+ClassF amp, is the most weight efficient , cost efficient way of getting something like 500 watts of power, but of course the amp is designed for mains power use and so structured for use wuth a good ground/earth, not floating around with the vagueries of weather

Perhaps a more convenient solution fine wire copper or brass mesh from a hobby shop Unscrew a rubber foot from the amp and wrap in the mesh. Some shield from coax cable pulled and squashed flat one end fitted under the foot and the other under a bush nut and glued to the amp casing. If exceedingly dry weather then some water /beer or piss under the foot. Fine mesh, should the amp end up on a table top at some point

I think its more likely an equipment fault putting mains voltage on the instrument, possibly through a capacitor. Charge 'em lots, Cookers, you put in a lot of effort.

Umm, they are geting charged, that is the problem :-)
