Does this EQ work?
It does.
Does this EQ work good?
Nah.
Does this EQ sound good?
Absolutely not.
It is easy to control, the housing is nice, but other then that everything is negative.
The EQ has a very loud and annoying 'hiss' when you turn it on, even when al the settings are set on zero! The problem is not the cables or power, it is the EQ itself.
When you cut or boost a certain frequency, the hiss escalates.
Also, the changes in sound are very minimum when you change stuff. I bought it to get rid of certain frequencies, but my sound got worse. And I know how to work a EQ, trust me.
It is very cheap, but it also sounds like that.
