This pedal is cheap, let's get that out of the way first. The sound isn't quite as good as that from a Boss. Besides that unreachable standard (it was 30 euros versus a lot more) it does its job. The sound is clear and the features are nicely adjusted to the desired sound. It is very reliable despite its all-plastic construction and sloppy activation feel. The internals are solid and it doesn't rattle or anything of that kind. It can be powered either by battery or 9V. I like it and I won't need something else.
This pedal has a great vintage tone, I love it and really recommend it, go on ebay and type in NUX CH-3, great pedal at a cheap price
