The garbage can do what?
All around your home are lots of great musical aids that you can't buy in a music store. The garbage can is one of my favorites, especially a large metal one. Be sure to clean it out well. The first time I used one for recording I ended up with glass all over my bedroom, I mean, studio carpet.

Hang the garbage can from the ceiling. Then hand a small amp inside of it. The amp shouldn't touch the can. Mic from above or place a PZM inside the can on the bottom. You also could place the can on the floor and use bricks as risers. Or, instead of hanging the amp, place it in the bottom of the can. The sound changes a lot with each variation.
