Status update: 8/11/2010 - Project #3 has unfortunately been retired due to damage beyond repair. I was building it in the garage. Took time off for a week of extremely hot, humid days followed by cold, dry nights. This made the MDF swell and pop the joints. The cab went all floppy :( The wood was cheap enough to write off. Making a new cab is easier in the long run. The conrol panel is undamaged :) I've learned a bit about better joints now too, which is good.
