Wow, I don't think a vintage fisher or scott would cut it for a 10 year old. They may sound great but are delicate and don't play loud. Kids will be kids and do something stupid and blow the amp.
How about a neat solid state amp and tube pre to get him started. Dynaco 120 and a pas 3? This would be much more abusable, play louder and still look vintage. You could even get him a matching tuner?
