hI James. It’s a Hammond. Model RMCS190313BK1 from Mouser. I add additional steel reinforcement inside the chassis.

He should have to have a firm electronic foundation, be able to solder, and do basic sheet metal work without cutting off any fingers. Usually a mic pre is the best starter project but a guitar amp or direct box would do.
