Hello,
I have the doomesque of issues, I built a 4x12 a year ago and until recently all was alright. But now there is a annoying buzz or rattling sound when I play cerrtain notes... and this especially occurs at high level of course.
I found out that the cab might be vibrating on certain freqs eventough I thought it it is a quite sturdy build (simple with glue and screws and side bracing)
Apparently adding extra bracing in the cab might help a bit to fix that.
Checked a bit online, but haven't found a convincing way to brace a 4x12 cab ...
I am also affraid that too much vibrations would damage the head lying on the cab...
Do any of you guys have any similar experience and/or bracing experiences ?
