I have been an old school Eden fan for years. The 2X10 Metro has always been my go to rig with Eden. With that said, the Metro amp with two channels seems to have an inherent issue with the channel switch. I have one that has been repaired and still suffers issues in this area. I only use the tube side so I was wondering if anyone has a proper fix for this or is there a way to bypass it to just make the tube side available? Options appreciated. Mark.
