Messing with the input tube is easy, you're right, soulinsane!
Tell me if you find any transparent values if you do this. So far the values i found out by calculating RC-constants directly changes the attitude of the whole amp. I tried the classic plexi values for V1b. It turns out ok, but every module immediatley starts to sound marshallesq. Which i don't mind BTW :wink:
