Full disclosure: I love this pedal. I have not yet contacted Thomann or Markbass but will do so if the wisdom of Talkbass can't help here. I got my Markbass Compressore late last week and I love the sound. However, the compression light does not light up most of the time. I can hear the compression and the limiting kicking in but the little amber bulb does not do anything. The only time it did anything was when I hit it with my hottest output bass on full with the gain, volume, attack, threshold and ratio knobs on full. After it lit up that time, it worked properly. When I moved it to the band's rehearsal space, no light again. Is there a dumb mistake I am making, something simple I am missing or is this just a faulty comp light? Thanks for any info you can give.
