I’m new here but have been reading up on things for awhile. Just recently purchased the MT15 and love it- it’s a beast of an amp! However, I cannot seem to alleviate the chassis rattle I’m hearing which is highly annoying. I have tightened every screw, changed and re-seated tubes (sovteks), and put padded tape between the cover and chassis where it touches and the screws go in. Still rattles, especially when the clean boost is engaged. It’s sitting on top of my EVH 212 cab, but I have tried moving it beside the cab, putting a mat underneath, etc- still rattles. Any fixes I haven’t tried yet? The amp is amazing but this issue is highly annoying!
