RunninReb 0 Posted March 26, 2015 Greetings, I purchased a Spider IV 75 off Craigslist and for a year, it served me quite well. When I turn the amp on now, I get a loud static like hiss. The hiss is present with both volumes turned completely down and it hisses even when a guitar chord is not plugged in. I did a reset and the static went away while during the reset process. Once the reset process was complete, the hiss returned. Any guidance would be greatly appreciated. Thanks! Share this post Link to post Share on other sites
