It requires a bit of preporation however some people have come up with clever methods for prepairing right in front of an audience with out them even knowing. before you spend 50 bucks on a needle I recomend you get Andrew Mains Shock FX.

The only problem with the paper clip method is you cant bleed. I use the needle on stage and the paper clips up close.
