Quoted from ChiroCop:
I was looking at the bottom of my LE cabinet...which is sitting next to my Aerosmith LE. Stern used particle board on the Aerosmith. MBr LE uses high quality plywood. This thing is solid.
Unbelievable, particle board, ya better have the dehumidifier running all summer, that stuff disintegrates with moisture, absolutely no excuse if that's the case, save what, $10/machine.
