So last night... Typical Friday night gig... Rushing to set up for an 8PM start. I start to play and my amp starts to fart at peaks. Im thinking, Compressor? Bad speaker? Bad preamp tube (just changed it), Amp just giving out (wt800) bad cable? Wireless? Battery? Guitar jack .... on and on..... Between sets im poking and pulling..... and then, I notice the speaker grate (410 XST) is pushed tightly against the cabinet. I quickly pulled it out some with a screwdriver and its fixed. Anybody ever experienced this? I'm thinking I should put some rubber spacers in there or something. Thoughts? How do you reinforce the cover?
