Hi every one, I've just received an MXR M87 Bass Compressor, bought from MusiciansFriend. It looks great, and give some cool tone for me in the first try. However, I have a problem with that. When I first plug the DC in, the meter leds are all turn on for a few seconds. After that, no more meter led, no matter how I set up the knobs and how loud I play... Reading the FAQ, it's written that I should adjust the input knob to reach 3-7 green leds on... However, I can't get them on Tried to unplug the DC and plug again, they are all on for a few seconds again I'm not sure if I did anything wrong or is it normal or is it a mal-function from MXR Could you please help with your experience? There's no meter led while I play the bass, even though if produces different sounds to the bypass sound.
