I wanted to give a report on how the mid control and other mods are working after playing through the amp and trying things out. The Framus mid control is great! I can get a sound similar to a Blackface Princeton with the mids cranked most of the way down, even closer with NFB loop added in. I'm glad I put a switch to bypass the mid control too, it's going to be handy to be able to keep it set how I want it and just turn it on or off. I'm liking the mid control enough that I wouldn't mind putting one in my 5f6a as well. There's some loss with it turned down but nothing I can't easily live with.
