As for the pedal, I like the size it’s not as big as the boss one as far as I know and it’s quite smooth when using it. Can’t really complain about that. But you can kind of tell it’s cheaply made, the input jack ring is plastic, and I know that’s going to break or crack some day, it’s bound to. There’s also an output label on the side but it’s plugged with a plastic piece. As if this used to be another type of pedal (volume pedal maybe?) and they just simply plugged up the input part and started selling this as an expression pedal. So it’s definitely somewhat of a cheap-ish pedal.
Overally it’s a cheap expression pedal. There are better ones out there and I’d recommend those if you have the extra cash to spend. These are nothing but decent.
