To complete my purchased Zoom G2, thus suits him perfectly. 6.50 euros for a life-changing not buy even batteries sion is obliged to be branch. This trasnfo is very useful and cheap compar to other brands of multi effects transformer. I believe it is essential to G2, would have to be provided bienq original too. I test with a noname transformer and it is much better even when the zoom has buzzes less. I am fully satisfied.
