Hey ya'all. I have a two year old Markbass Compressore that is making a static and buzzing sort of noise. The noise is constant but sometimes there are bad moments of added static (that's the best way I can describe it). The noise goes away when the pedal is switched off or removed from my signal chain. I once had a bad tweeter that made a similar noise but you can hear this plain as day (even worse) thru headphones and even if I roll the tweeter all the way off my cab. I originally thought it was a bad cable and then thought the tube had become microphonic because when I tapped the pedal with my fingers over the tube it would make quite a bit of noise and the footswitch seemed to be kind of loud. the pedal makes the noise with no cable or bass plugged into the input and for the record I have checked all my cables. The volume and gain or at noon or just under. I have it set so the volume is just slightly louder or the same than when the pedal is off. I opened the pedal and found the tube was only halfway plugged into the socket. I remove the tube and cleaned the terminals with Deoxite on a pipe cleaner and used a small airbrush cleaning brush to clean the socket with small dabs of Deoxite. Still made the noise. I replace the JJ ECC81 with a JJ ECC83 that was good and the noise continued. Today I went to Radio Shack and bought a 12V 1.5A power supply and tried it and the noise is still there.... actually the plug adapter is a bit long and it added a hum so it was worse! LOL! I am questioning the footswitch because even though the solder joints look good where it's attached to the circuit board the footswitch is loose and moves on the terminals. Maybe that's normal. I though maybe the footswitch just plugged on because it was loose but it doesn't appear to. The switch kind of looks like the one pictured. I ordered the pedal from GC May 23, 2010 and Markbass has a 2 year warranty so I'm not sure how lenient they would be for warranty repair but I'll contact them tomorrow. Just wondered if there was anything I'm overlooking. Thanks in advance.
