Matches well what I expect with the DS2

Works perfectly. It can work without batteries, they only serve to power the diode.

hello everyone I would like to buy this product but I am not sure and I would like your opinion. I am currently playing in a rock band and we are starting to play concerts, I am missing a pedal, so I can play a solo with the sound I want without having to stop 4 bars before to adjust my amp. is it enough? thanks in advance to you
