I think it's great that this project is going so well. The aluminium
looks wonderful---I'll definitely join the queue to buy one!

In the photo http://empeg.comms.net/files/115755-newface2.gif, it looks
as if there is a chunk taken out of the left side of the piece surrounding
the volume knob. Is that there for a reason?

I do think the curve in the upper right corner could be nicer. The wavy
curve doesn't quite match either the radius or the centre of any other
curves, so it looks a bit out-of-place. I've done some mock-ups with
other curves; please look and see if you like any of them better. They
should all keep clear of the works behind.
