Apparently my MXR Super Comp has a mechanical bypass. It mutes/passes the bass signal even when there is no power. My beef now is that it makes a click audible through the amp when I switch it on or off. Regardless of whether it's powered or not. Is this normal/common for hard bypass switches? I'm thinking of returning it for a replacement but would like to know first. Dunlop hasn't replied yet and I'm getting antsy FWIW, it's a good comp. But the attack knob works backwards IMO. Turning it up slows down the compressor reaction to peaks. Thanks for any words of wisdom.
