BigDLarry Posted April 26, 2020 Share Posted April 26, 2020 Started a few years ago and I tried everything. Dozen cables, dozen guitars, active/passive pickups, dozen power cables, dedicated power from the fuze box, on a UPS battery backup for clean power, nothing helps. On all modes/settings/effects combinations, my amp will randomly have what I can only describe as an extremely slow phaser effect? It slowly loses all low/mids and then gets all screechy/hissy/whiney. Suddenly like as if you popped your ears and they stop ringing it goes back to normal. I looked at all of the boards, all caps and connections look good. At this point do I scrap it and buy another amp? Boards for these things aren't cheap and aren't guaranteed to not have issues in the future. Quote Link to comment Share on other sites More sharing options...
psarkissian Posted April 27, 2020 Share Posted April 27, 2020 Older product like that, probably likely it's an old and oxidized solder point on a surface mount component, allowing a partial ground lift, resulting in the clock frequency to demodulate into the audio band. Not a user repairable issue. Should be served at a Line 6 authorized service center that knows the product. Quote Link to comment Share on other sites More sharing options...
