The panels look good and the cases are neat. What are the cases made from. MDF board I noticed the panels are recessed quite a bit too. I`m guessing this is to protect the knobs etc. I`m curious how deep your cases are I`m working on getting my circuits behind panels and in several small cases at the moment. I`m wondering if they have a tendency to want

to fall over when the leads are inserted. I must say, you have done a really great job with these. It seems to make sense putting the sockets on one side and the pots on the other. It just eliminates a lot of fiddling around for pots under layers of cables. The panels look good and the cases are neat. What are the cases made from.
