Classic Style Guitar Amp 1.0.0

Blame that on my lack of experience. I presume by now you've learned of the rescaling  gizmo in  the World Editor. It's the icon that looks like a box with an arrow coming out of the upper right corner. If not. load the amp file into the Editor. The amp parts should be grouped but if not position your camera so you can drag your mouse all around the amp without catching an unwanted object. Then click on the Rescaling gizmo, hold down the Left Shift key on your keyboard. A small square will appear where the three vertices meet. While holding down the Shift key, drag your cursor down until you get the size you want the amp to be.
