Was your suffering from a lack of Mids? That’s what mine is like. Even though in theory the gain channels should still break up from the pre amp the same, the Koch sounds different, but in a good way. I dug out the manual last night. I forgot I had it but it says you can put any power Valve configuration in there. Even mix them up in pairs.
I’m not going to be using tonnes of gain for this project. I play a lot of clean Nile Rogers style stuff. If I do any solos it’s all lower gain stuff. I still like the heavier end of things too. Perhaps I’ll be able to pursued the others to do something sleazy like VH Dirty Movies! I’d better get practicing for that one 😈
