JoeViking 1 Posted March 9, 2014 Hello, The volume keeps dropping down/cutting out (usually not totally) on all channels on my Spider III. The master is not that high at all....this is my practice amp.....and it is not the guitars or the cords.....any ideas? I have noticed some posts about speaker vibration but I don't think that is the issue here. Thanks! Joe V. Quote Share this post Link to post Share on other sites
