weight on cabinets

[Mick D.]

I wouldn't worry about it too much.
I have 2 Epifani UL-110 cabs.
The other night at rehearsal I had my 2-space with the UL-500, a 4-space with my Cyberbass rig, and a 6-space with my PA all stacked up on them.

I think they actually liked it.

Something like that happened to my Mesa cabinets- I put my Bass 400 on top and it literally split both cabients in two, one right after the other. I still played the show though, as the head was undamaged by the fall.

This is probably the funniest mental image I've had in a while...
