bought it for the same reason that most people will be buying it for, that reason being it being a cheap alpha omega pedal for a good price but there's an issue with this unit where the distortion circuit has a loud beep whenever the distortion is engaged. tried different power supplies, different sockets, tried the instrument out and the xlr out and both of those have the same issue, tried running the instrument into a di box and it still happens. it's a good pedal and very useful the its just an eq di pedal for me at this point sadly.
